Case : Read the passage and answer the question(s). A charged particle whose mass is 19.9 ×10-27 kg and charge is 1.6×10-19 C moves with a speed of 3×105 m/s at right angle to a magnetic field of 0.75 T.

What is the force acting on the charge particle?

3.6×10-15 N 3.6×10-20 N  3.6×10-14 N 3.6×10-12 N

3.6×10-14 N

F = q v B  m = 19.9 x 10-27 Kg ; v = 3 x 105 m s-2 ; q = 1.6 x 10-19 C ; B = 0.75 T F = 3.6×10-14 N
