Question

52. A block of mass 5 kg is at rest on a rough inclined surface. If angle of inclination of plane is 60°, then force applied
by it on block is
(1) 50 N
(2) 253N
(3) 25 N
​(4) 505. answe,,.r is 50N ​

Answer 1

Answer:

F=5×10=50 N

Also according to ""Newton's Third Law of Motion”, “every action has an opposite and equal reaction”. Since the “force” on the block is its weight which is given by mg, so the “force” on the block with an inclination angle 60 would also be the same as mg.
