Question

Write down the work done to rotate an electric dipole to rotate in uniform electric field from stable configuration to most unstable configuration. *

1 point

PE

2PE

-PE

-2PE​

Answer 1

Answer:

2PE

Explanation:

• Stable Configuration is when then angle between Electric dipole and Electric field is 0°
• Most unstable configuration is when the angle between Electric dipole and Electric field is 180°

WORK DONE = -PE { COS (final angle) - COS (initial angle)}

So

W.D. = -PE { COS (180°) - COS (0°)}

= -PE {-1-1}

= -PE {-2}

= 2PE
