Newton’s second law of motion states that the acceleration of the object is directly proportional to the net force acting on it and will be inversely proportional to the mass of the object.The direction of the acceleration will be in the direction of the net force

Mass m = 2 kg

The weight of an object is the gravitational force exerted by the earth on the object. It is proportional to the mass of the object

W=mg

W=2 g

So the right answer is option c. 2g

Euler’s equations of motion for a rigid body can be interpreted as a rewriting of Newton’s second law for rotations in a rotating frame. They basically tell us the sum of the torques equals the rate of change of the body’s angular momentum, In the rotating frame. Do we then not need to take into account inertial forces when computing the torques in rotating coordinates?

Given a block which is at rest on a perfectly flat smooth table with no friction. You push with your hand horizontally on the block with some force. The force on the block = 16.0 N and the acceleration of the block is $2.00\text{}m/{s}^{2}$. If the force on the block is tripled then the acceleration of the block will be which of these?
