1.	A wire, which passes through the hole in a small bead, is bent in the form of quarter of a circle. The wire is fixed vertically on ground as shown in the figure. The bead is released from near the top of the wire and it slides along the wire without friction. As the bead moves from A to B, the force it applies on the wire is A. always radially outwardsB. always radially inwardsC. radially outwards initially and radially inwards laterD. radially inwards initially and radially outwards later.
Answer» Correct Answer - D When bead is at `A`, the force it applies on the wire is redially inwards. When it reaches at `B`, it strikes the surface and pushed outwards. Thus, force is radially outwards.

As shown in Fig. the two sides of a step ladder `BA` and `CA` are `1.6 m` long and hinged at `A`. A rope `DE, 0.5 m` is tied half way up. A weight `40 kg` is suspended from a point `F, 1.2 m` from B along the ladder` BA`. Assuming the floor to be fricionless and neglecting the weight of the ladder, find the tension in the rope and forces exerted by the floor on the ladder. (Take `g = 9.8 m//s^(2))` (Hint. Consider the eqilibrium of each side of the ladder separately.)
