Question

14. Two short dipoles are placed as shown. Torque on dipole of dipole moment p2 is nearly ​

Answer 1

Answer:

the correct ans is option one

Answer 2

Answer:

Concept :

A pair of opposing charges, q and -q, separated by a certain amount of space, d, are referred to as an electric dipole. Electric dipoles in space always point from negative charge -q to positive charge q by default. The dipole's centre is defined as the intersection between q and -q. A pair of electric charges with two opposite signs and equal magnitudes spaced apart is the most basic type of electric dipole.

Explanation:

• Torque on dipole of dipole moment P2 is nearly, it is represented in vector symbols.
• z = $P_{2}$ × $E_{1}$
• z = $P_{2}$ $E_{1}$ sin180°
• z = 0
• In this case, the force vector is at an angle of 180° (or radians), pointing straight at r.
• Again, pushing away from the axis of rotation won't result in any rotation, and the mathematics again corroborate this intuition.
• The value of the torque is once more equal to zero since sin(180°) = 0.
