Problem 33P

Two objects attract each other gravitationally with a force of 2.5 × 10−10 N when they are 0.25 m apart. Their total mass is 4.0 kg. Find their individual masses.

Step-by-Step Solution:
Step 1 of 3

Solution 33P Consider the torque produced by the frictional force on your foot is net torque.but we ignore this frictional torque and others. We know that force acting on system F = 7.0 N r is distance from the chair’s rotation axis=0.40 m The angular acceleration is = 1.8 rad/m and angular acceleration is greater at the angle is 90 0 The total moment of inertia is given by the expression I = net I = rFsin()/ I = (0.40 m)(7.0 N)sin(90 )/(1.8 rad/s ) 2 I = 1.6 kg/m 2 Here we know from above result the mass distribution is so closer to axis of rotation ,so moment of inertia is small.
