# PROBLEM ON ELECTROMAGNETISM

**Electricity and Magnetism**Level pending

A neutral atom of atomic mass number 100 which is stationary at origin in gravity free space emits an alpha particle(A) in Z-direction. The product ion is P.

A uniform magnetic field exists in X-direction. Disregard the electromagnetic interaction between A and P.

If the angle of rotation of A after which A and P will meet for the first time is '22n/175' radians , FIND THE VALUE OF "n".
