A beam of `alpha, beta, gamma` rays is travelling along X - axis. When it enters a region of uniform magentic field, `alpha` particles are deflected towards the Y-axis , then

Options

A. 1. `gamma` rays will turn towards Z-axis
B. 2. `beta " and " gamma` rays will also turn towards (Y axis)
C. 3. `gamma` rays will turn towards (-Yaxis)
D. 4.`beta` rays will turn towards (-Yaxis)

Answer

D

Explanation

`gamma` rays are e.m. waves. They will continue to travel along the X-axis. Positively charged `alpha` rays are deflected towards Y-axis. `beta` rays are negatively charged electrons, they will turn towards the Y-axis.
