Problem 34P

Calculate the effective value of g, the acceleration of gravity, at (a) 3200 m, and (b) 3200 km, above the Earth’s surface.

Step-by-Step Solution:
Step 1 of 3

Solution 34P 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 is the torque around a defined axis N/m I is moment of inertia(kg/m ) 2 2 is angular acceleration (rad/s ) = I is the rotational along of newton’s second law F = ma Net torque on object is given by = I = (2.0 kg/m )(4.0 rad/s )2 = 8.0 N/m The units are correct and relatively small.torque magnitude is consistent with size of moment of inertia and angular acceleration.
