Question:

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.

Calculate the centripetal acceleration associated with the charged particle.

Options:

1.81×1010 m/s2 

1.81×1012 m/s2

 2.64×1012 m/s2 

2.64×1010 m/s2 

Correct Answer:

1.81×1012 m/s2

Explanation:

Acceleration : a = \(\frac{qvB}{m}\)

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

a = 1.81×1012 m/s2
