Question

An electric dipole experiencing maximum torque in uniform electric field possesses-----------potential
energy.

Answer 1

Answer:

- ZERO POTENTIAL ENERGY. OR MINIMUM. POTENTIAL ENERGY.

EXPLANATION.

AT MAXIMUM TORQUE , WE KNOW ANGLE BETWEEN DIPOLE AND ELECTRIC FIELD IS 90°

TOU = P × E = PE SIN THETA . SIN 90° = 1 ( MAXIMUM)

= PE.

,

BUT,

WE KNOW,

POTENTIAL ENERGY= - P . E

= - PE COS THETA COS 90° = 0 ( MINIMUM )

= 0.... [ ANS ]
