Acharge of 8.4 × 10–4 c moves at an angle of 35° to a magnetic field that has a field strength of 6.7 × 10–3 t. if the magnetic force is 3.5 × 10–2 n, how fast is the charge moving? 9.1 × 10–5 m/s 1.3 × 10–4 m/s 7.6 × 103 m/s 1.1 × 104 m/s ive taken this test twice and gotten a 68 both times lol

The velocity of a point charge moving under the influence of electric and magnetic fields is the velocity of that moving charge . The velocity of the moving charge will be 1.1 × 104 m/s.

Lorentz force is defined as the force acting on point charge when it is moving in an electric and magnetic field. Under the electric and magnetic field, a force is act on the charge known as the Lorentz force.

The given data in the problem is ;

q is the value of charge = 8.4 × 10–4 C

θ is the angle to the magnetic field= 35°

B is the magnetic field strength = 6.7 × 10–3 T.

v is the velocity if moving charge =?

Mathematically the Lorentz force is given by
