Question

Assertion: An object can be accelerated with a uniform pace.

Reason: For this to happen , it must be acted upon by unbalanced force​

Answer 1

According to newton's first law of motion, an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

so if forces acting on the object is balanced then the object will be in equilibrium and it will not have any acceleration.

cannot comment about option B because if initially object is at rest then it will be always at rest .

Answer 2

Assertion: An object can be accelerated with a uniform pace.

Reason: For this to happen , it must be acted upon by unbalanced force​

Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.

According to newton's first law of motion, an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
