Two discs A and B touch each other as in figure. A rope tightly wound on A is pulled down at 2m//s^(2) . Find the friction force between A and B if slipping is absent. .

In the network as shown in figure. Each resistance r is of 2Omega find the effective resistance between points A and B.

Two speres of radii r and 2r touching each other the force of attraction betweeen them is proportional

In the arrangement shown in figure, coefficient of friction between the two blocks is mu=1//2 . The force of friction acting between

Each resistance shown in figure is 2 Omega . The equivalent resistance between A and B is

A block is suspended by two light ropes r_(1) and r_(2) as shown in figure . Then what is the tension the rope r_(2)

A block is suspended by two light ropes r_(1) and r_(2) as shown in figure . Then what is the tension the rope r_(2)

Circles C_(1) and C_(2) of radii r and R respectively, touch each other as shown in the figure. The lime l, which is parallel to the line joining the centres of C_(2) and C_(2) is tangent to C_(1) at P and intersects C_(2) at A,B.If R^(2)=2r^(2) , then angleAOB equals-

Two discs A and B are in contact and rotating with angular velocity with angular velocities omega_(1) and omega_(2) respectively as shown. If there is no slipping between the discs, then
