If the end `A` of a wire is irradiated with `alpha`-rays and the other end `B` is irradiated with `beta`-rays. Then

Options

A. A current will flow from A to B
B. A current will flow from B to A
C. There will be no current in the wire
D. A current will flow from each end to the mid - point of the wire

Answer

A

Explanation

The end A of the wire will be +ve because `alpha` particles are +vely charged and the end B will be -ve because `beta` particles are -vely charged. Thus `V_A gt V_B`. Hence current will flow from A to B.
