A body of mass m is situated in potential field `U(x)=U_(o)(1-cospropx)` where, `U_(o)` and `prop` are constants. Find the time period of small oscillations.

Explanation

To find the time period of small oscillations for a body of mass \( m \) situated in the potential field \( U(x) = U_0 (1 - \cos(\text{prop} \cdot x)) \), we can follow these steps:

### Step 1: Identify the Potential Energy Function
The potential energy function is given as:
\[ U(x) = U_0 (1 - \cos(\text{prop} \cdot x)) \]
