Question

sum of force is 8 kg wt. the magnitude of resultant of two force is 4kg wt and it is right angle to smaller force. find the force​

Answer 1

Answer:

The forces will be f1 = 3 anf f2 = 5

Explanation:

According to the problem the sum of the forces is 8 kg

let the two forces are, f1 and f2

therefore, f1 + f2 = 8

              =>f2 = 8 - f1

The resultant force of these two forces is f(resultant) = 4 kg

The angle between the resultant force and the forces is 90°

Now we can n assume that,

f2^2 = f1^2+ f(resultant)^2

f2^2       = f1 ^2 + 4^2

=>(8-f1)^2 = f1 ^2 + 4^2

=> f1 = 3

therefore,

f2 = 5
