Options

  1. AAccording to the station clocks, two babies are born at the exact same instant, one in Kanpur and the other in Agra.
  2. BAccording to the station clocks, two babies are born at the exact same instant, one in Kanpur and the other in Agra.
  3. CAccording to the station clocks, two babies are born at the exact same instant, one in Kanpur and the other in Agra.
  4. DAccording to the station clocks, two babies are born at the exact same instant, one in Kanpur and the other in Agra.

Correct answer

D. According to the station clocks, two babies are born at the exact same instant, one in Kanpur and the other in Agra.

Step-by-step solution

A wooden block, initially at rest on the ground, is pushed by a force which increases linearly with time t . Which of
F=ma⇒a=Fm=ktm\mathrm{F}=\mathrm{ma} \Rightarrow \mathrm{a}=\frac{\mathrm{F}}{\mathrm{m}}=\frac{\mathrm{kt}}{\mathrm{m}} a vs tt will be straight line passing through origin.
