Question

Resultant of two equal forces acting at right angles to each other is 14 newton find magnitude of force

Answer 1

A = B

∅ = 90°

Resultant force = 14N

Resultant = √(A²+B²)

14=√(A²+A²)

14=√(2A²)

14 = √2A

14/√2 = A

A = 7√2 N

Cheers!

Answer 2

Resultant of 2 equal perpendicular vectors is given by

mod(Resultant)=square root(2) × mod(given vector)

Let magnitude of equal forces of x Neach.

14=root(2)×x

x=14/root(2) N

x=7×root(2) N
