The number of values of such that the straight line y=4x+c touches the curve is‐

 1
 2
 infinite
The correct answer is: 2
We need to find the number of values of such that the straight line y=4x+c touches the curve .
Therefore, there are two values of c.

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
