MCQ

A force of $100 \,dynes$ acts on a mass of $5\, gram$ for $10\, sec$. The velocity produced is ......... $cm/sec$

A
$2000$
✓
$200$
C
$20$
D
$2$

✓

Answer

Correct option: B.

$200$

b
(b)$v = u + at = 0 + \left( {\frac{F}{m}} \right)\;t = \left( {\frac{{100}}{5}} \right) \times 10 = 200\;cm/\sec $
