### Problem Statement

For a system of charges shown in Figure, find:

a) The electric field vector (magnitude and direction) at point \( C \).

b) The potential difference between points \( C \) and \( B \).

c) The minimum work necessary to move a +1µC charge from point \( B \) to point \( C \).

### Figure Explanation

The diagram provided illustrates a setup with two charges and specific distances between the points of interest:

- There are two charges: 
  - \( Q_1 = +6 \text{ nC} \) is positioned 4 meters below the origin (on the \( y \)-axis).
  - \( Q_2 = -3 \text{ nC} \) located at the origin of the coordinate system (intersection of the \( x \) and \( y \) axes).

- Point \( B \) is situated 7 meters to the right along the \( x \)-axis.

- Point \( C \) is 7 meters to the right along the \( x \)-axis and 4 meters up along the \( y \)-axis relative to the origin.

### Notation
- \( Q_1 \) and \( Q_2 \) are the charges located at specific points.
- \( B \) and \( C \) are two distinct points where computations are required.
- \( (\vec{E}_C) \) denotes the electric field at point \( C \).
