Question 170: Laws of Motion

Question

A block of mass 200 g is kept stationary on a smooth inclined plane by applying a minimum horizontal force F = $$\sqrt{x}$$N as shown in figure.

The value of x = _____________.

Accepted Answer

$$F 	imes {1 \over 2} = 0.2 	imes 10 	imes {{\sqrt 3 } \over 2}$$
$$ \Rightarrow F = 2\sqrt 3 $$
$$ \Rightarrow F = \sqrt {12} $$ N
$$	herefore$$ $$x = 12$$
