Solution

The correct option is B $Δ (m v)$
As we know that momentum (p) =MAASS $\times$ VELOCITY(vector quantity)
hence chance in momentum( $Δ$ p)= $m_{2} v_{2} - m_{1} v_{1}$ = $Δ$ (mv)
where $m_{1}$ = $m_{2}$ =m
$Δ$ v= $v_{2} - v_{1}$

A body of mass m moving with a velocity v is acted upon by a force. Write expression for change in momentum when v→c.

The correct option is B Δ(mv)As we know that momentum (p) =MAASS×VELOCITY(vector quantity)hence chance in momentum(Δp)=m2v2−m1v1=Δ(mv)where m1=m2=mΔv=v2−v1
