Question : A particle moving in a straight line with uniform acceleration is observed to be a distance 𝑎 from a fixed point initially. It is at distances 𝑏, 𝑐, 𝑑 from the same point after 𝑛, 2𝑛, 3𝑛 second. The acceleration of the particle is

(A) $\dfrac{c-2b+a}{n^{2}}$

(B) $\dfrac{c+a+b}{9n^{2}}$

(D) $\dfrac{C-b+a}{n^{2}}$

Answer : option (A)

Solution :

A particle moving in a straight line with uniform acceleration is observed to be a distance 𝑎 from a fixed point initially. It is at distances 𝑏, 𝑐, 𝑑 from the same point after 𝑛, 2𝑛, 3𝑛 second. The acceleration of the particle is
