JEE Main 5 April 2024, Shift 1, Physics Q51

Question 51 of 90 in this shift, Physics question 21 of 30, Section B.

A body moves on a frictionless plane starting from rest. If

S_n

is distance moved between

t=n-1

and

t=n

and

S_{n-1}

is distance moved between

t=n-2

and

t=n-1

, then the ratio

\frac{S_{n-1}}{S_n}

\left(1-\frac{2}{x}\right)

for

n=10

. The value of

x

is ________.
