mαѕѕ = 2kg

αmglє σf ínclínαtíσn between block and horizontal line is 30°

coefficient of friction = 0.7

Force that will slide the body is mgsin∅

2×9.8×0.5
= 9.8N

Limiting or static friction will be kmgcos∅
= 0.7×2×9.8×√3/2
=11.88N

as the limit infection is more than the force tends to slide the body the frictional force on body will be 9.8N and body will be at rest
