Question

Two forces 7N and 3N are simuntaneoysly acting on a body.What is the. (1)Maximum resultant (2)Minimum resultant. (3)What will be the resultant if the forces act at the right angle to each other?​

Answer 1

Answer:

Maximum resultant: 7N + 3N = 20N (towards the same direction).

Minimum resultant: 7N - 3N = 4N (In the opposite direction).

Resultant Force at right angles: ($F^{2}$) = ($7^{2}$) + ($3^{2}$)

$F^{2}$= 49 + 9 = 58

F = $\sqrt{58$ = 7.62 N
