What is the distance from the Earth’s center to a point outside the Earth where the gravitational acceleration due to the Earth is of its value at the Earth’s surface?

Solution 35P When the torque is applied on an object that rotating about field axis then that object will undergo angular acceleration.the angular acceleration is quantitative expression of the change in angular velocity that a spinning object undergoes per unit area. The angular acceleration in terms of torque is defined as torque=(moment of inertia)*(angular acceleration) = I = /I The moment of inertia about an axis passing through center of axis is I = mr /2 Where r is radius of disk. To solve this problem we have to knowing some concepts like torque,moment...
