Which of the following forces in non conservation one ?

Answer»

`3hat(i) +4hat(j)`
`4xhat(i) + 3yhat(i)`
`3x^(2) HAT(i) + 4y^(2) hat(j)`
`y^(2)hat(i) + x^(2)hat(j)`

Solution : for conservationforce `F_(x)=(-DU)/(dx), F_(y) = (-dU)/(DY)`
`(deltaF_(x))/(deltay)=(deltaF_(y))/(DELTAX)=(DELTA^(2)U)/(deltaxdeltay)`
