Gravitation question

2020 · 5 Sep · Shift 2 · Q42

JEE MainPhysicsGravitationMCQ+4 / −1
The acceleration due to gravity on the earth’s surface at the poles is g and angular velocity of the earth about the axis passing through the pole is ω\omegaω. An object is weighed at the equator and at a height h above the poles by using a spring balance. If the weights are found to be same, then h is (h << R, where R is the radius of the earth)
