A particle starts from rest with uniform acceleration a. Its velocity after \( \mathrm{n} \) seconds is \( \mathrm{v} \).
\( \mathrm{P} \)
The displacement of the particle in the last two seconds is :
W
(A) \( \frac{2 \mathrm{v}(\mathrm{n}-1)}{\mathrm{n}} \)
(B) \( \frac{\mathrm{v}(\mathrm{n}-1)}{\mathrm{n}} \)
(C) \( \frac{\mathrm{v}(\mathrm{n}+1)}{\mathrm{n}} \)
(D) \( \frac{2 \mathrm{v}(2 \mathrm{n}+1)}{\mathrm{n}} \)
