Question
The minimum area of triangle formed by tangent to the ellipse and coordinate axes‐
 ab



The correct answer is: ab
Given, that a triangle is formed by tangent to the ellipse and coordinate axes, we need to find the minimum area of the triangle formed.
Therefore, the minimum area is ab.

A block placed on a rough inclined plane of inclination ( =30°) can just be pushed upwards by applying a force "F" as shown. If the angle of inclination of the inclined plane is increased to ( = 60°), the same block can just be prevented from sliding down by application of a force of same magnitude. The coefficient of friction between the block and the inclined plane is
