Solution

The correct option is B $f = m \times a$
According to Newton's second law of motion,
When an external force is applied on an object, the object gets accelerated in the direction of force.
Therefore, force is proportional to acceleration.
So, $f = m a$
m=mass of the body.
a= acceleration of the body.

The correct form of Newton's second law is:
(a) $F = \frac{△ p}{△ t}$ (b) $F = m \frac{△ v}{△ t}$ (c) $F = v \frac{△ m}{△ t}$ (d) F = mv

F = [Km * (V-U)]/t; can be rewritten as:

F = [K $\times$ m $\times$ (v - u)] / t; can be rewritten as:

$F = k \times m \times \frac{(v - u)}{t}$ ; where k is a constant can be rewritten as:

F = $K \times m \times \frac{(V - U)}{t}$ ; where K is a constant can be rewritten as:
