A disc of radius 2m and mass M is rotating with 200 rpm. Find torque required to stop disc in 10 secs.

A force vecF=(3hati+4hatj)N is acting on a point mass m=((1)/(2))kg at a point A(2m,2m) . Find the angular acceleration of the line OA at this instant.

A force vecF=(3hati+4hatj)N is acting on a point mass m=((1)/(2))kg at a point A(2m,2m) . Find the angular acceleration of the line OA at this instant.

Two equal and opposite forces are allplied tangentially to a uniform disc of mass M and radius R as shown in the figure. If the disc is pivoted at its centre and free to rotate in its plane, the angular acceleration of the disc is :
