An electric field `vec(E ) = hat(i) `Cx exists in the space, where C = 10 V/`m^(2)` . Taking the potential at (10 m, 20 m ) to be zero, find the potential at the origin.

Explanation

To find the potential at the origin (0, 0) given the electric field \( \vec{E} = Cx \hat{i} \) where \( C = 10 \, \text{V/m}^2 \), and knowing that the potential at the point (10 m, 20 m) is zero, we can follow these steps:

### Step-by-Step Solution

1. **Identify the Electric Field**:
The electric field is given as:
\[
\vec{E} = 10x \hat{i}
