Vedclass · Answer

(A) When a high energy $X-$ray beam falls on a metallic ball,photoelectrons are emitted from the surface of the ball due to the photoelectric effect. As the ball loses electrons,it acquires a net positive charge. Since the ball is placed in a uniform electric field,it experiences an electrostatic force $F = qE$. Because the charge $q$ is positive,the direction of the force is the same as the direction of the electric field. Therefore,the ball will be deflected in the direction of the electric field until it reaches a new equilibrium position.

$A$ small metal ball is suspended in a uniform electric field with the help of an insulated thread. If a high energy $X-$ray beam falls on the ball,then the ball
