Question

a force of 8N acts on amass and produce an acceleration of 2ms-2 if the force required to produce an acceleration of 8ms-2 a)8N b)16N c)32N d)0N

Answer 1

Force acting on the mass = 8 N

Acceleration (a) = 2 m/s^2

Let the mass of the body be m

Force = mass × acceleration

$m = \frac{Force}{acceleration}$

$m = \frac{8}{2}$

m = 4 kg

Now, the new acceleration is 8 m/s^2

Force required =?

Force = mass × acceleration

Force = 4 × 8

Force = 32 N

Hence, the force required to produce 8 m/s^2 acceleration is 32 N

Option (c) is correct.
