Question

An electron moving in a variable magnetic field B, having a variable linear velocity v, will remain rotating in a circle of constant radius r only, when (A) B is held constant (B) v is held constant (C) v and B both are held constants (D) angular velocity is constant

Tardigrade Admin · Accepted Answer

The electron moving with linear velocity will remain rotating in a circle of constant radius r in a magnetic field, only when v and B both are held constant.

Q. An electron moving in a variable magnetic field B, having a variable linear velocity v, will remain rotating in a circle of constant radius r only, when

B is held constant

v is held constant

v and B both are held constants

angular velocity is constant

The electron moving with linear velocity will remain rotating in a circle of constant radius r in a magnetic field, only when v and B both are held constant.
