Question

A force of 60 N acting perpendicular to a force
of 80 N. magnitude of resultant force is
(A) 20 N
(B) 70 N
(C) 100N
(D) 140 N​

Answer 1

Answer:

100N

Explanation:

[c] 100 Newton

using Pythagoras theorem

i.e sqrt[60^2+80^2]

Method two:

Let the force be : 80i+60j

Now take the magnitude. of the vector
