4-1.Newton's Laws of Motion
easy
કણનો બળ વિરુધ્ધ સમયનો આલેખ આપેલ છે. $0$ અને $ 8 sec $ વચ્ચે વેગમાનમાં કેટલો વધારો થશે?
A
$ - 2\pi \,newton \times second$
B
$Zero\;newton \times second$
C
$ + 4\pi \,newton \times second$
D
$ - 6\pi \,newton \times second$
Solution
(b)As the area above the time axis is numerically equal to area below the time axis therefore net momentum gained by body will be zero because momentum is a vector quantity.
