Question

An eletric dipole with two
Changes +5 uc
& -5 uc are separated
by
distance
of 10 cm a placed in
uniform
electric field of intensity 200 V/m
calculate the torque acting
dipole af encess of dipole
makes
angle 30 degree with speed.
200 v/m

​

Answer 1

$torque \: = p \: e \: \sin( \alpha )$

P = 2a×q

P = 2×0.1×5

P= 1 Cm

Applying this in the equation given above

$t = 1 \times 200 \times \sin(30 ) \\ \\ t = 200 \times \frac{1}{2 } \\ \\ t = 100$

SO THE TORQUE IS 100 Nm
