$\color{grey}{\sf \large \underline{Question :-}}$
The sum of the magnitudes of two forces acting at point is 18 and the magnitude of their

resultant is 12. If the resultant is at 90° with the force of smaller magnitude, what are the,

magnitudes of forces


(a) 12, 5
(b) 14, 4
(c) 5, 13
(d) 10,8

Answer 1

Answer:

Thrust is a force or a push. When a system pushes or accelerates mass in one direction, there is a thrust (force) just as large in the opposite direction. ... Thrust is used to describe how strongly an engine pushes.

Answer 2

Answer:

Correct option is (C)

5,13

Step-by-step explanation:

Let the magnitude of smaller force is P, the magnitude of larger force is Q and the resultant force is R.

As the resultant force makes 90

∘

with the smaller force P then Q forms the hypotenuse of the triangle.

Thus, it can be written as,

Q ^2 −P ^2=R ^2

Q ^2 −P ^2=(12) ^2

Q ^2 −P ^2 =144 (1)

The sum of magnitudes of two forces is given as,

P+Q=18

Q=18−P (2)

Substituting the value from equation (2) in equation (1), we get

(18−P) ^2 −P °2 =144

P=5N

Substituting the value of P in equation (1), we get

Q=18−5

=13N

Thus, the magnitude of the forces are 5N and 13N.
