Question

iv)
Science
A proton enters a uniform magnetic field of 5T with velocity
4 x 107 ms - at right angles to the field. The magnetic force acting on
the proton is (charge on a proton = 1.6 x 10-19 C)
​

Answer 1

Whe know that the negative charge on the electron and the postive charge on the proton are equal. Suppose that these magnitudes differ from other by 0.00010%
