Find the reading of th spring balance shown in figure. The elevator is going up with an accelertion of g/10, the pulley and the strng are light and the pulley is smooth.

Explanation

To solve the problem of finding the reading of the spring balance when the elevator is accelerating upwards with an acceleration of \( g/10 \), we can follow these steps:

### Step 1: Understand the Effective Gravity
When the elevator is accelerating upwards, the effective acceleration due to gravity increases. The effective gravitational force can be calculated as:
\[ g_{\text{effective}} = g + a \]
where \( a \) is the acceleration of the elevator. In this case, \( a = \frac{g}{10} \), so:
