A body is moving down along inclined plane of angle of inclination q.

1.	A body is moving down along inclined plane of angle of inclination q. The coefficient of friction between the body and the plane varies as m = 0.5x, where x is the distance moved down the plane. The body will have the maximum velocity when it has travelled a distance x given by
Answer» `x = 2 TAN theta ` `x = (2)/(tan theta)` `x = SQRT2 cot theta ` `x = (sqrt2)/(cot theta)` ANSWER :A
