Question

How the force on the conductor will change if (a) angle between I and B is increased from 0° to 90° (b) length of conductor is doubled.​

Answer 1

a) F = GMm/r*r

Hence the force will decrease as r increases.

b) Resistance is directly proportional to length and inversely to current.

Hence the force will decrease because resistance increases decreasing the current.
