Kinematics Question 154

Question: P, Q and R are three coplanar forces acting at a point and are in equilibrium. Given P = 1.9318 kg wt, sinθ1= 0.9659, the value of R it’s ( in kg wt) [CET 1998]

Options:

A) 0.9659

B) 2

C) 1

D) 12

Show Answer

Answer:

Correct Answer: C

Solution:

Psinθ1=Qsinθ2=Rsin150

1.93sinθ1=Rsin150

R=1.93×sin150sinθ1=1.93×0.50.9659=1
