A positively charged particle is release...

A positively charged particle is released from rest in an uniform electric field. The electric potential energy of the charge

A

remains a constant because the electric field is uniform.

B

increases because the charge moves along the electric field.

C

decreases because the charge moves along the electric field.

D

decreases because the charge moves opposite to the electric field.

Text Solution

Verified by Experts

The correct Answer is:
C
Positive electric charge always flows in direction of decreasing potential (i.e., from higher potential to lower potential) and hence along the direction of decreasing potential energy.

A proton is released from rest in a unifrom electric field. Does the proton's electric potential energy increase or decrease? Does the proton move towards a location with a higher or a lower electric potential.

Two point charges having charge +Q, –q and mass M, m respectively are separated by a distance L. They are released from rest in a uniform electric field E. The electric field is parallel to line joining both the charges and is directed from negative to positive charge. For the separation between particles to remain constant, the value of L is (K=(1)/(4piin_(0)))
