Physics Question from JEE Main 2026 · 21 January, Shift 1

Initially a satellite of $100 \, \text{kg}$ is in a circular orbit of radius $1.5R_E$. This satellite can be moved to a circular orbit of radius $3R_E$ by supplying $a \times 10^6 \, \text{J}$ of energy. The value of $a$ is _____ . (Take Radius of Earth $R_E = 6 \times 10^6 \, \text{m}$ and $g = 10 \, \text{m/s}^2$).
