A particle with total energy E is moving in a potential energy region U (x). Motion of the particle is restricted to the region when

  • Option 1)

    U (x) > E

  • Option 2)

    U(x) <E

  • Option 3)

    U (x) =0

  • Option 4)

    U(x) \leq E

As discussed in

If only conservative forces act on a system, total mechnical energy remains constant -

K+U=Eleft ( constant ight )

Delta K+Delta U=0

Delta K=-Delta U

-

 

 As the particle is moving in a potential energy region

\therefore K.E \geq 0

Total Energy = F = K.E + P.E

                          = U(x) \leq E


Option 1)

U (x) > E

This solution is incorrect

Option 2)

U(x) <E

This solution is incorrect

Option 3)

U (x) =0

This solution is incorrect

Option 4)

U(x) \leq E

This solution is correct
