Q137 / 180 · KCET 2015 · Physics

Pick out the statement which is incorrect.

A
The tangent drawn to a line of force represents the direction of electric field.
Correct answer
B
The electric field lines forms closed loop.
C
A negative test charge experiences a force opposite to the direction of the field.
D
Field lines never intersect.

Solution

Statement 1 is correct - The tangent drawn to a line of force represents the direction of electric field. Statement 2 is incorrect - The electric field lines never form closed loops. Statement 3 is correct - A negative test charge experiences a force opposite to the direction of the field Statement 4 is correct - Field lines never intersect.

Hence, the correct answer is option: 'B'.
