A block of mass \(m\) is placed on a flat horizontal surface, and the coefficient of friction between the block and the surface is \(\mu\). A force \(F_A\) is applied to the block from above, and a force \(F_R\) is applied to the right. In all situations being considered below, the block remains at rest. Let \(f\) be the force of friction on the block.
               
Consider the statements:
(P) \(f\) increases if \(m\) is increased.
(Q) \(f\) increases if \(F_A\) is increased.
(R) \(f\) increases if \(F_R\) is increased.
1. Only P is True.
2. Only Q is True.
3. P, Q are True.

The two blocks \(A,~B\) are connected by an inextensible string, and are lying on a horizontal surface. The blocks move under the action of forces of magnitudes \(F_1\) and \(F_2,\) as shown in the figure. The surface exerts non-zero frictional forces \(f_A,~f_B\) (towards right).

Consider the following situations:
(P) \(f_A,~f_B>0\) (Q) \(f_A,~f_B<0\)
(R) \(f_A>0,~ f_B<0\) (S) \(f_A<0,~ f_B>0\)

Which of the above, are possible? Assume that the string is taut.
1. (P) or (Q)
2. (R) or (S)
3. Any of (P), (Q), (R), (S)
