Practicing Success
If we shift a body in equilibrium from A to C in a gravitational field via path AC or ABC : |
The work done bt the force \(\vec{F}\) for both paths will be same WAC > WABC WAC < WABC None of the above |
The work done bt the force \(\vec{F}\) for both paths will be same |
For the path AC : WAC = Fs cos (90o - θ) = mgs sin θ = mgh For the path AB : WAB = Fa cos 90o = 0 For the path BC : WBC = Fh cos 0o = mgh So that : WAB + WBC = mgh = WAC i.e. WABC = WBC |
