NEET 2021 Physics Equations of Motion MCQ Question

Type: MCQ-numerical-Medium-Class 11

A small block slides down on a smooth inclined plane, starting from rest at time t = 0. Let Sₙ be the distance travelled by the block in the interval t = n−1 to t = n. Then, the ratio SnSn+1\frac{S_n}{S_{n+1}} is :

A

2n−1

B

2n

C

2n+1

D

2n−1

Correct Answer

Option B

Detailed Explanation

The distance traveled by the block in each interval is proportional to the square of the time. Thus, the ratio of distances SnSn+1\frac{S_n}{S_{n+1}} simplifies to 2n12n-1.
