Answer 2

SOLUTION

Given,

the velocity of protons, v= 4× 10^5 m/s

Uniform magnetic fiel, B= 0.3T

Angle made by particle with magnetic field 60°

The magnetic force will act like centripetal force.

Therefore,

r= mv/qB

r= 1.67×10^-27 ×4×10^5 sin 60°/1.6 × 10^-19 ×0.3

=) 1.2× 10^-2

=) 1.2cm

Pitch is the distance moved along the magnetic field in one rotation.

Therefore,

=) T= 2πr/v sin theta = 2.175 × 10^-7S

=) P= v cos theta. T

=) 4× 10^5 × 1/2 × 2.175 × 10^-7

=) 4.35cm
