Question

In a region with a uniform electric field, where the potential v1 is 1.3 V at position y1 = 26 cm and v2 is 3.9 V at y2 = 28 cm, what is the potential at position y3 = 32 cm?

Answer 1

The potential at position y3 = 32 cm is 9.1 V.

Step-by-step explanation:

To find the potential at position y3 = 32 cm, we can use the formula:

V = V1 + (V2 - V1) * (y - y1) / (y2 - y1)

Plugging in the given values:

V3 = 1.3 V + (3.9 V - 1.3 V) * (32 cm - 26 cm) / (28 cm - 26 cm) = 1.3 V + 2.6 V * 6 cm / 2 cm = 1.3 V + 2.6 V * 3 = 1.3 V + 7.8 V = 9.1 V
