Question
If a tangent to ellipse + = 1 makes an angle with x axis, then square of length of intercept of tangent cut between axes is



 None of these
The correct answer is:
Let tangent is += 1
Slope is tan = – S… (1)
square of length of intercept is
=
Length is … (2)
Now use value of tan from (1)

Two blocks A and B of equal masses m kg each are connected by a light thread, which passes over a massless pulley as shown in the figure. Both the blocks lie on wedge of mass m kg. Assume friction to be absent everywhere and both the blocks to be always in contact with the wedge. The wedge lying over smooth horizontal surface is pulled towards right with constant acceleration a ( ). (g is acceleration due to gravity). Normal reaction (in N) acting on block A.

A light inextensible string connects a block of mass m and top of wedge of mass M. The string is parallel to inclined surface and the inclined surface makes an angle with horizontal as shown in the figure. All surfaces are smooth. Now a constant horizontal force of minimum magnitude F is applied to wedge towards right such that the normal reaction on block exerted by wedge just becomes zero. The magnitude of acceleration of wedge is
