Q. Assertion :A small electric dipole is moved translationally from higher potential to lower potential in uniform electric field. Work done by electric field is positive. Reason: When a positive charge is moved from higher potential to lower potential, work done by electric field is positive.

Under a constant Electric field of 5 N/C, a positive charge moves such that its Kinetic energy is increased by 10 J. Assuming no other force acting, the work done by the field is?

Q. The force exerted by an electric field on a charge of 3 micro-coulomb is

6 x 10^{- 4} N

. What is the electric intensity of the field?

Under a constant Electric field of 5 N/C, a positive charge is moved against the field by an external agent such that the P.E of the system is increased by 10 J. Does this imply that the work done by external agent is +10 J?

Q. A Force F is put on a test charge Q by an electric field. What is the strength of the electric field at that location?
