MHT CET 2026 Physics question
Two stones of masses m and 3 m are whirled in horizontal circles, the heavier one in a radius and the lighter one in radius r. When both the stones experience same centripetal forces, the tangential speed of lighter stone is 'n' times that of the value of heavier stone. The value of 'n' is
Answer: (C)
Solution
Centripetal force . Lighter stone: . Heavier stone: . Equal forces give , so and . The speed of the lighter stone is 3 times that of
