When a n electric dipole is in st able equilibrium, in uniform electric field, its electrostatic potential energy is ......

A

`-pE`

B

pE

C

0

D

`prop`

Text Solution

Verified by Experts

For stable equilibrium we should have
`U= U_("min") implies ` When `theta=0^(@)` we have
`U =- pE = U_("min")`
