## Question:

A {eq}\rm 0.32 \ \mu C {/eq} particle moves with a speed of 19 m/s through a region where the magnetic field has a strength of 0.99 T.

(a) At what angle to the field is the particle moving if the force exerted on it is {eq}\rm 4.8 \times 10^{-6} \ N {/eq}?

(b) At what angle to the field is the particle moving if the force exerted on it is {eq}\rm 3.0 \times 10^{-6} \ N {/eq}?

(c) At what angle to the field is the particle moving if the force exerted on it is {eq}\rm 1.0 \times 10^{-7} \ N {/eq}?

## Magnetic force on a Moving Charge

When a charged particle enters in a region of magnetic field. It will experience a magnetic force which is proportional to the product of charge, velocity and magnetic field.

Let us recap important data from the question

• Charge on the particle {eq}q = 0.32 \times 10^{-6} C {/eq}
• Speed of the particle {eq}v = 19...
