Question

An elechic dipole of dipole moment 4x10^minus5 cm
is placed in a uniform electric field of 10^minus3 Nc1
making an angle of 30° with the direction of the
field. Determine the torque experienced by the dipole
​

Answer 1

Answer:

torque = 2 × 10 ^ -10

Explanation:

given ,

dipole moment ( P ) = 4× 10 ^-5 cm

=4 × 10 ^-5 × 10 ^-2 m

Electric field ( E ) = 10^-3 N / C

Angle = 30°

Torque = P × E sin ●°

= 4× 10 ^-7 × 10^ -3 × sin 30°

=4 ×10 ^-10 × 1/2

= 2 × 10 ^- 10
