A large tray of mass

{M}

has in it a cubical block of ice of mass

{m}

and edge length

{L}

. The ice starts melting. The shift in the height of centre of mass of system (ice + tray) is

View answer and explanation

Correct option: C

\frac{1}{2} \frac{{mL}}{({m}+{M})}

; downward

Option C (

\frac{1}{2} \frac{{mL}}{({m}+{M})}

; downward) is correct because when the ice melts, the center of mass of the ice lowers by L/2, and the overall shift in the center of mass is calculated considering both masses.
