A pendulum bob has potential energy U₀ when held taut in a horizontal position.The bob falls until it is 30$\degree$ away from the horizontal position,when it has potential energy U_A.It continues to fall until the string is vertical,when it has potential energy U_B.Compare its potential energies at O,A,and B. A)U₀ = U_A = U_B. B)U_A- U_B = 2U₀. C)U_A - U_B = U₀ - U_A. D)U₀ = U_B = 2U_A. E)U₀ - U_A = 2(U_A -U_B).

The Answer of A pendulum bob has potential energy U₀ when held taut in a horizontal position.The bob falls until it is 30$\degree$ away from the horizontal position,when it has potential energy U_A.It continues to fall until the string is vertical,when it has potential energy U_B.Compare its potential energies at O,A,and B. A)U₀ = U_A = U_B. B)U_A- U_B = 2U₀. C)U_A - U_B = U₀ - U_A. D)U₀ = U_B = 2U_A. E)U₀ - U_A = 2(U_A -U_B).
