Solution
The correct option is C force
slope = dK/dx
total energy(E) is always constant
E = Kinetic + Potential = K + U
diffrentiating w.r.t. x we get
dE/dx = dK/dx + dU/dx
0 = dK/dx + dU/dx
slope = -dU/dx = Force (by definition)
slope = dK/dx
total energy(E) is always constant
E = Kinetic + Potential = K + U
diffrentiating w.r.t. x we get
dE/dx = dK/dx + dU/dx
0 = dK/dx + dU/dx
slope = -dU/dx = Force (by definition)
