A force F=t is applied to a block A as shoen in figure where t is time in seconds. The force is applied at t=0 seconds when the system was at rest. Which of the following graph correctly gives the frictional force between A and horizontal surface an a function of time t. [Assume that at t=0 , tension in the string connecting the two blocks is zero].
