According to Newton's second law, the acceleration produced in a body is:

1. inversely proportional to the force applied on it
2. directly proportional to the force applied on it
3. not dependent on force
4. none of these

The correct form of Newton's second law is —

1. F = $\dfrac{Δp}{Δt}$

2. F = m $\dfrac{Δv}{Δt}$

3. F = v $\dfrac{Δm}{Δt}$

4. F = mv

The acceleration produced in a body by a force of given magnitude depends on —

1. size of the body
2. shape of the body
3. mass of the body
4. None of these
