Vedclass · Answer

(A) Work is defined as the product of force and displacement (length): $W = F 	imes d$.If the unit of force $F$ is increased by $4$ times,the new force $F' = 4F$.If the unit of length $d$ is increased by $4$ times,the new displacement $d' = 4d$.The new unit of energy $W'$ will be: $W' = F' 	imes d' = (4F) 	imes (4d) = 16 	imes (F 	imes d) = 16W$.Therefore,the unit of energy is increased by $16$ times.

$(D)$ Power	$(IV)$ $Nm^{-2}$

If the unit of force and length each be increased by four times,then the unit of energy is increased by $...$ times.
