Questions
The resultant of two forces cannot exceed
a
average of the forces
b
algebraic sum of the two forces
c
difference of the two forces
d
none
detailed solution
Correct option is B
If α be the angle between the forces P→and Q→, then their resultant is given by R→⇒R =Since (1+cosα) is positive , magnitude of resultant R is less than or equal to i.e R ≤ (P+Q), equality sign holds good when (1-cosα) = 0 i.e α =00.Talk to our academic expert!
