Question

Contact force (F.) between two bodies is the resultant of force of friction and normal reaction.
Contact force for shown position is (g = 10 ms?)
(A) 40N
(B) √1616 N
(C)4N
(D) None of these
​

Answer 1

Answer:

c)is a answer 4n......please follow me

Answer 2

mg= N+20√2sin 45

6×10 = N+20√2sin45

N= 60-20√2 1/√2

N = 40

static = UsN

0.2 × 40 = 8

kinetic=UkN

0.1 × 40 = 4
