Question

Assertion: A line of force has sudden breaks.
Reason: An electrostatic line of force is a continuous curve.
A. if both Assertion and Reason are true and the Reason is correct explanation of the Assertion.
B. If both Assertion and Reason are true but Reason is not the correct explanation of the Assertion.
C. if Assertion is true, but the Reason is false.
D. if both Assertion and Reason are false

Answer 1

Correct Answer - a
The tangent at a point an the electric line of force tells the direction of electric field charge from point to point. So, line of force are curved lines. Further they are continous curves and cannot have sudden breaks otherwise it will indicate the absence of electric field at the break point.
