Question

A force F1 acting on a 2 kg body produces an acceleration of 2.5 ms - 2. Another force F2 acting on a
5 kg body produces an acceleration of 2 ms - 2. The forces F1 and F2 are
[ ]
a) 5 N, 10 N
b) 10 N,5N
c) 1 N, 2N
d) 2 N,1N​

Answer 1

Answer:

HI

Explanation:

Newton's second law states the rate of change of momentum is directly proportional to the unbalanced force applied.

From which we get, F = ma

In 1st case

mass, m1 = 2kg

and

acceleration, a1 = 2.5 m/s²

So, F1 = 2 × 2.5 = 5N

In 2nd case

m2 = 5kg

and

a2 = 2m/s²

So, F2 = 5 × 2 = 10N

Therefore, F1 / F2 = 5/10 = 1/2
