there is no clear answer can be given for this, you can think in terms of charge induced on the body of phonograph after is is cleaned, and this charge may attract the phonograph.

Two parallel beams of light P and Q are incident normally on a prism and the transmitted rays are brought to focus with the help of a convergent lens as shown. If the intensities of the upper and lower beams immediately after transmission from face AC are 4I abd I, respectively, find the resultant intensity at the focus.
