Question

The maximum and minimum resultants of two forces are in the ratio 7:3. The ratio of the forces is
(A) 4:1
(C) 17:13
(B) 5:2
(D) 49:9​

Answer 1

Answer:

B. 5 / 2

Explanation:

Given,

R maximum=(A+B)=7------eq^n(1)

R minimum=(A-B)=3------eq^n(2)

From eq^n (1) &(2)

A+B=7

A-B=3

———

2A=10

A=10/2

A=5

Putting the value of A in eq^n(1)

5+B=7

B=7-5

=2

Now, According to the question. The ratio of forces be

A/B= 5:2

Mark me brainliest :)))

Answer 2

OPTION D

Explanation:

because in option D if we squares the number we will get 7:3
