Physics Question from JEE Main 2023 · 24 January, Shift 1

A weightless pulley P is attached at the apex of a double inclined frictionless surface whose two faces make angles of $60^\circ$ and $30^\circ$ with the horizontal. A massless string passes over the pulley and connects a $4 \, \text{kg}$ block resting on the $60^\circ$ face to a $1 \, \text{kg}$ block resting on the $30^\circ$ face. The tension in the string will be (if $g = 10 \, \text{m/s}^2$):
