36. A particle is moving with velocity v-Ktyi+x)whe k is constant. The general equation of its pa(c# constant) is(4) yx2 + c

Answer»

As v= k(yi + xi)vₓ= Ky so dₓ/dt = Kyvy= Kₓ so dy/dt = Kₓ

dividing both equationsdy/dₓ= dy/dt divide dx/dt = Kx/Ky =x/yyou will getydy= xdx

integrating the equationy²/2 = x²/2 + c

Hence, option (1) is correct.
