Question

Statement-1: A small metal ball is suspended in a uniform electric field with an insulated thread. If high energy X-rays beam falls on the ball, the ball will be declected in the electric field.
Statement-2: X-rays emit photoelectrons and metal and metal becomes negatively charged.
A. Statement-1 is true, Statement-2 is true and Statement-2 is correct explanation of Statement-1.
B. Statement-1 is true, Statement-2 is true, but Statement-2 is not a correct explanation of Statement-1.
C. Statement-1 is true, but Statement-2 is false
D. Statement-1 is false, but Statement-2 is true.

Answer 1

Correct Answer - c
When high energy X-rays fall on the ball, the metal ball will emit photoelectrons, leaving the positive charge on the ball. As a result of it, the ball is deflected in the direction of the electric field. Thus, the statement-1, is true but statement-2 is true.
