MHT CET 2026 Physics question
What should be the angular velocity of earth due to rotation about its own axis so that the weight at equator becomes of initial value? (g= acceleration due to gravity, R-radius of earth)
Answer: (B)
Solution
At the equator (latitude ) the effective acceleration due to gravity is . The weight becomes of its initial value, so . Then \dfrac{3g}{5}$ =
