Answer
F = m x a
Reason — On the basis of experiments Newton concluded that :
(i) The acceleration produced in a body of given mass is directly proportional to the force applied on it. i.e., a ∝ F (if mass remains constant)
(ii) The force needed to stop a given acceleration in a body is directly proportional to the mass of the body. i.e., F ∝ m (if acceleration remains the same).
Hence, F ∝ ma or F = Kma
Here, K is a constant and we get,
F = m x a
