A force F acts on a particle kept on a rough surface as shown in the figure. The particle is at rest. Find the net force applied by ground on the particle.

A

120 N

B

20 N

C

100 N

D

`20sqrt(37)`N

Text Solution

Verified by Experts

The correct Answer is:
d

N=120 N f=20 N
Total force by ground =`sqrt(120^(2)+20^(2))=sqrt(1400+400)=sqrt(4800)=10sqrt(4xx37)=20sqrt(37N)`
