Physics · MOTION IN A STRAIGHT LINE
हिन्दीA body starting from rest moves along a straight line with uniform acceleration. It covers a distance \( x_1 \) in the first \( t \) seconds and an additional distance \( x_2 \) in the next \( t \) seconds. The relation between \( x_1 \) and \( x_2 \) is:
Correct answer · Option 3
\( x_2 = 3x_1 \)
Explanation
Distance in first \( t \) seconds is \( x_1 = \frac{1}{2}at^2 \). Total distance in \( 2t \) seconds is \( x_1 + x_2 = \frac{1}{2}a(2t)^2 = 4x_1 \). Hence, \( x_2 = 3x_1 \).
