Question

A 12Mev protron is moving at an angle of 30 to uniform magnetic field of 2.0tesla what is magnetic Force on the protron?​ please give answer

Answer 1

Answer:

Given, Magnetic field B=2T

Potential gap ΔV=100kV

We know that, r=

qB

mv

⇒V=100×10

3

=10

5

volts

So, KE gained in each revolution =e(V)+e(V)=2e(V)=2e×10

5

Thus, number of revolution N=

2×10

5

20×10

6

=100revolution
