Question

For a particle executing SHM the displacement x is given by x = A cos ωt. Identify the graph which represents the variation of potential energy (P.E.) as a function of time t and displacement x.

 

Options

• I, III

• II, IV

• II, III

• I, IV

Answer 1

I, III

Explanation:

The particle begins to oscillate in x = A cos ωt from an extreme position. Thus, its potential energy is greatest at time t = 0.
