Directions: In the following question, two statements are given. One is assertion and the other is reason. Examine the statements carefully and mark the correct option.
Assertion (A): Kinetic energy is zero to move a positive test charge from infinity to the particular point against the electrostatic force due to the electric field.
Reason (R): Kinetic energy is directly proportional to the mass, that's why kinetic energy is zero for test charge.
