Q6.8Multiple choice
The potential energy function for a particle executing linear SHM 1 2 is given by V ( x ) = kx where k is the force constant of the oscillator (Fig. 6.2). For k = 0.5N/m, the graph of V(x) versus x is shown in the figure. A particle of total energy E turns back when it reaches x = ± x m . If V and K indicate the P.E. and K.E., respectively of the particle at x = +xm, then which of the following is correct?
This question refers to a figure in the original PDF.
- (a)V = O, K=E
- (b)V = E, K=O
- (c)V < E, K=O
- (d)V = O, K < E. Fig. 6.2
