Question

if a body of mass 2kg is moving with an acceleration of 5 metre per second square the net force acting on a body is?
​

Answer 1

Given:-

• Mass of the body = 2 kg
• Acceleration (a) = 5 m/s²

To Find:-

• Force acting on the body = ?

Explanation:-

Using formula :-

$\huge \bf\fbox{F = ma}$

➙ F = ma

➙ F = 2 × 5

➙ F = 10 N

$\fbox{➙ F = 10 N}$

Answer 2

Answer:

Given mass = 5 kg. velocity = 4m/s net force will be 0 .this is because object moving with a uni form speed has zero acceleration .there is no change in velocity .

And according to the newton's second law of motion we know ,acceleration is directly proposional to force.

Explanation :-

if acceleration = 0

Force = mass × acceleration

Force = mass × 0

Force = 0

thus , net force acting on body is zero
