Question

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






a) I, III
b) II, III
c) II, IV
d) I, IV​

Answer 1

Answer:

1,III

II, IV

II, III

I, IV

Answer :

A

Explanation:

Solution :

In (S.H.M.), at extreme position, (P.E.) is maximum when

t=0,x=A

i.e., at time (t = 0), the particle executing (S.H.M.) is at its extreme position.

Therefore (p.E.) is max. The graph (I) and (III) represent the above charcteristics.
