Name the physical quantity whose SI unit is volt/meter. Is it a scalar or a vector quantity ?

Explanation

To solve the question, we need to identify the physical quantity whose SI unit is volt per meter and determine whether it is a scalar or vector quantity.

### Step-by-step Solution:

1. **Identify the SI Unit**: The question states that the SI unit is volt per meter (V/m). We need to determine what physical quantity is measured in this unit.

2. **Relate Voltage and Electric Field**: We know that electric potential (voltage) is related to electric field. The electric field (E) can be defined as the change in electric potential (V) per unit distance (d):
