Question

A force of 100 N applied on an object accelerates it with an acceleration of 2ms-2. How much force is required to produce the same acceleration when an identical object of same mass are tied with the first object?

1.50 N
2.100 N
3.300 N
4.200 N​

Answer 1

Explanation:

let the mass be 'm'

f = ma

=> 100 = m × 2

=> m = 100/2 = 50 kg

New mass is 2m = 2×50 = 100 kg

f = 100 × 2 => 200 N is the force required

Answer 2

Answer:

200N

Explanation:

F=ma

100 =m×2

m=50

total mass=50+50

100Kg

acc.=2m/s^2

F= 100×2

F=200N
