Which of the following statements about electric field lines is incorrect?
They point from positive toward negative charges. … Electric field lines never cross each other and point from positive toward negative charge. They do not form closed loops and always start from a positive charge and end on a negative charge. The correct answer is C.
Which is not correct for electric field lines?
Electric field lines do not form any closed loops. The statement is true because the electric field lines start from positive charge and end on negative charge. Since the starting and ending point of the electric field lines is different, a loop can never be closed.
Which of the following statements is true about electric field lines?
Electric field lines are close together in regions of space where the magnitude of the electric field is strong and are farther apart where it is weak. … Electric field lines point away from positive charges and toward negative charges. e. Electric field lines are continuous; they do not have a beginning or an ending.
Which is correct about electric field and electric field lines?
Electric field lines never intersect. In an uniform electric field, the field lines are straight, parallel and uniformly spaced. The electric field lines can never form closed loops, as line can never start and end on the same charge. These field lines always flow from higher potential to lower potential.
Which of the following statement is correct the electric field at a point is?
Electric field at a point is continuous if there is no charge at that point. And the field is discontinuous if there is charge at that point. So both options (b) and (c) are correct.
Which of the following is wrong for electric lines of force?
They always form closed loops.
Why do electric field lines go from positive to negative?
The direction of the electric field is always directed in the direction that a positive test charge would be pushed or pulled if placed in the space surrounding the source charge. … As such, the lines are directed away from positively charged source charges and toward negatively charged source charges.
Which of the following are not properties of lines of forces in an electric field?
Which of the following aren’t the properties of lines of force of an electric field? Lines of force always intersect. Lines of force start from negative charge and terminate at te positive charge. The tangent to line of force at a point gives the direction of the electric field.
In which conditions does electric field lines contract lengthwise?
As electric field lines emanates from positive charge and go to negative charge, hence they get contracted longitudinally, this is the indication of force of attraction b/w unlike charges.
Which of the following figure represents electric field lines correctly?
If we have a negative charge, then its electric field lines are radially inward direction as shown in the above figure. Because electric field lines start from infinity where the positive charge is supposed to be existing and end at a negative charge. Thus, option (B) is the correct answer.
Can electric field lines curve?
This means that the overlapping curved field lines will average out as a straight field line, through the middle of the point-charge pairs. The outermost edges of the electric field, on the other hand, will have nothing to interfere with, and remain curved.
Do electric field lines provide information about nature of charge?
Also, the electric field lines always originate from positive charge and end up at negative charge. From this, we can determine the direction of field and nature of the charge. … Thus, the electric field lines provide information about field strength, direction of electric field and nature of the electric charge.
