1.	(a) Define torque acting on a dipole moment p Placed in a uniform electricfield E. Express it in the vector form and point out the direction alongPwhich it acts.(b) What happens if the electric field is non-uniform ?(C) What would happen if the external field E is increasing (i) Parallel top (ii) anti-parallel to p ?
Answer» The torque is DEFINED as the product of the charge and electric field acting on the charge. The vector notation of the torque is τ=p×E. The direction on both p and E is acting perpendicular to both. The electric field is non- UNIFORM then the net force acting on them is not equal to zero. The electric field in both CASES are increasing with POINT P. But the DIFFERENCE came in the direction when they are in parallel, then both are in same direction. When they are in perpendicular the direction is opposite to each other.

Answer»

The torque is DEFINED as the product of the charge and electric field acting on the charge.

The vector notation of the torque is τ=p×E.
The direction on both p and E is acting perpendicular to both.

The electric field is non- UNIFORM then the net force acting on them is not equal to zero.
The electric field in both CASES are increasing with POINT P. But the DIFFERENCE came in the direction when they are in parallel, then both are in same direction.
When they are in perpendicular the direction is opposite to each other.
