Q: A block of mass m = 3 kg slides on a rough inclined plane of coefficient of friction 0.2. The resultant force offered by the plane on the block.

(a) $\displaystyle 6\sqrt{13} N$

(b) $\displaystyle 6\sqrt{17} N$

(c) $\displaystyle 6\sqrt{15} N$

(d) $\displaystyle 6\sqrt{11} N$

Ans: (a)

Sol: (a) $\displaystyle \sqrt{N^2 + f^2}$
