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?
Answer & explanation
Correct answer: option 3
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
