Question

b. 0.64 ms c. 0.40 ms d. 0.49 ms e. 0.80 ms A 2.0-C charge moves with a velocity of (2.0i +4.0j +6.0k) m/s and experiences a magnetic force of (4.0i - 30j +12K) N. The x component of the magnetic field is equal to zero. Determine the z component of the magnetic field. a. 3.0 T b. +3.0 T c. +5.0 T d. -5.0 T e. +7.5 T inted along the positive x axis in a 440: +30i) mT.

Answer 1

The magnetic force on charge q moving at velocity v in presence of magnetic field B is

F =qlū x B)

The y-component of the force is

Fy=q(u.B. - V.B.)

Given x-component of the magnetic field is zero B_{​​​​​​x}​​​=0

Fyr -qurB:

D: B: = - Ur

Substituting values

(-30 N) (2.0 C) x (2.0 m/s)

B. = +7.5 T
