Question

this is a question of physics chapter 1 electric charges and fields for class 12th ​

Answer 1

Answer:

Formula for calculating this torque is P×E

do the cross product is this order only

Explanation:

P = charge * length of dipole

(put the magnitude of charge only)

direction of P vector is from negative to positive charge

I hope this helps

Answer 2

Answer:

torque = dipole × electric field × sin(theta)

$torque = \frac{4}{100} \times 8 \times {10}^{ - 9} \times 2.5 \times {10}^{10} \times \sin(60) \\torque = 80 \times {10}^{ - 2} \times \frac{ \sqrt{3} }{2} \\ torque = 40 \sqrt{3} \times {10}^{ - 2} \\ torque \: = 0.4 \sqrt{3}$
