A particle starts its motion from rest under the action of a constant force. If the distance covered in first 10 seconds is S1\mathrm{S}_1 and that covered in the first 20 seconds is S2\mathrm{S}_2 then :

Options

  1. AS2=S1\mathrm{S}_2=\mathrm{S}_1
  2. BS2=2 S1\mathrm{S}_2=2 \mathrm{~S}_1
  3. CS2=3 S1\mathrm{S}_2=3 \mathrm{~S}_1
  4. DS2=4 S1\mathrm{S}_2=4 \mathrm{~S}_1

Correct answer

D. S2=4 S1\mathrm{S}_2=4 \mathrm{~S}_1

Step-by-step solution

\mathrm{s}=\frac{1}{2} \mathrm{at}^2 s2 s1=(2010)2=4 s2=4 s1\begin{aligned}& \frac{\mathrm{s}_2}{\mathrm{~s}_1}=\left(\frac{20}{10}\right)^2=4 \\ & \mathrm{~s}_{2}=4 \mathrm{~s}_{1} \end{aligned}
