Comprehension: (Q. 19)
If a man has a velocity varying with time given as \( v= \)
\( \mathrm{P} \) \( 3 t^{2}, v \) is in \( \mathrm{m} / \mathrm{s} \) and \( t \) in sec then:

W
Bâsed on above comprehension choose the correct option(s) regarding displacement of particle:
(1) Displacement of particle after 2 seconds of his start is \( 8 \mathrm{~m} \)
(2) Displacement of particle after 2 seconds of his start is \( 12 \mathrm{~m} \)
(3) Ratio of displacement of particle during first 2 seconds and next 2 seconds is \( 1: 7 \)
(4) Ratio of displacement of particle during first 2 seconds and next 2 seconds is
\( 7: 1 \)
