On a particle placed at origin a variable force `F=-ax`(where a is a positive constant) is applied. If U(0)=0, the graph between potential energy of particle U(x) and x is best represented by:-

A particle free to move along x-axis is acted upon by a force F=-ax+bx^(2) whrte a and b are positive constants. For ximplies0 , the correct variation of potential energy function U(x) is best represented by.

A particle is placed at the origin and a force F = kx is acting on it (where k is a positive constant). If U (0) = 0, the graph of U(x) versus x will be (where U is the potential energy function)

A particle is placed at the origin and a force F=Kx is acting on it (where k is a positive constant). If U_((0))=0 , the graph of U (x) verses x will be (where U is the potential energy function.)
