Question

a hundred kg body is resting on horizontal plane having coefficient of friction 0.2 a force of 19 6 newton is required to pull the body horizontally find the acceleration developed by the body​

Answer 1

Answer:

0 m/s²

Explanation:

The Given data

1. Mass - 100 kg
2. Coefficient of friction - 0.2
3. Force applied - 196 N

Acceleration of body - ????

Accelaration due to gravity = 9.8 m/s²

Step 1 :-

Force of friction =μMg where, μ is coefficient of friction

                                                 M is mass given

                                                 g is the acceleration due to gravity

= 100×0.2×9.8 = 196 N

Step 2 :-

$Ma = Force applied - frictional force$

Using that formula and the given data...

196 N - 196 N = M(a)

0= 100(a)

a =0 m/s²

As the net force is 0, there is no movement
