49. A block A of mass, 10kg lies on a smooth horizontal surface. A force of 10 N is applied on the block as
shown in the figure. Calculate the normal reaction force on block A by horizontal surface. ( 8 = - 10 ms ?)
30°
Options:
(a) 50 N
(b) 100 N
(c) 95 N
(d) ON​

Answer 1

Answer:

Given

Mass (M) = 10kg

Co-efficient of friction (K)=0.5

Horizontal force = 100 N

g=10

s

2

m

Solution

Normal reaction =M×g=10×10

Normal reaction =100N

Friction force (F)=K×0.5=0.5×100=50N

F=Ma

50=10×a

a=5

s

2

m
