easy

$5 \,g$ ના કણ પર $3 \,seconds$ સમય સુધી $50\, dynes$ નું બળ લાગે ,તો બળનો આધાત કેટલો થાય?

A$0.15 \times {10^{ - 3}}\,N{\rm{ - }}s$
B$0.98 \times {10^{ - 3}}\,N{\rm{ - }}s$
C$1.5 \times {10^{ - 3}}\,N{\rm{ - }}s$
D$2.5 \times {10^{ - 3}}\,N{\rm{ - }}s$

Solution

(c) Impulse = Force $×$ Time $= 50 × 10^{-5} × 3$
$= 1.5 × 10^{-3}\ N-s$
