Which of the following can be used to determine the charge on the sol?

A

Ampere's law

B

Stoke's law

C

Fleming's left hand rule

D

Fleming's right hand rule

Text Solution

Verified by Experts

The correct Answer is:
B
Stoke.s law established that if radius (r) sphere having velocity (v) moves through the viscous medium `(eta)` , the viscous force opposing the motion of the sphere is `F = 6 pi eta r vecv`
