Verified Answer :

According to Newton's second law of motion, Force is the product of mass and acceleration of the object.
So, F = m a

Here, m = 210 Kg
a = 2.4 10⁵ m/s²

Substitute their values, 
F = 210 2.4 10⁵ N
F = 504 10⁵ N
F = 5.04 10⁷ N

In short, Your Answer would be Option B

Hope this helps!
