Question

magnetic force of on moving positive charge is defined by f bar = q v bar × B bar the v bar = velocity of the body B bar = magnetic field if velocity of charged particle is directed vertically upwards and magnetic field is directed towards east then direction of magnetic force is​

Answer 1

Explanation:

Deduce the formule for time period and radius of charged particle moving through a magnetic field this is correct answer of given question

Answer 2

Explanation:

Derivation

Resistance (R) = Voltage × Current-1 . . . . (1)

Since, voltage (V) = Electric Field × Distance = [Force × Charge-1] ×
