Answer 1

Answer:

V = 2000 volts.

Step-by-step explanation:

It is given that ,

Work Done ,W = 20 Mj

Charge ,q = 100uc

We have to calculate the potential difference between these points.

Firstly we change convert the unit here .

As we know that

➛ 1Mj = 10⁶ J

So,

➛ 20Mj = 20×10⁵ J

➛ 20Mj = 2×10⁷ J

Now,

converting the unit of charge into columbs.

➛ 1 uc = 10⁻⁶ C

➛ 100uc = 100 × 10⁻⁶ J

➛ 100uc = 10⁻⁴ J

Using formula we get

V = W/q

Substitute the value we get

➛ V = 2×10⁷/10⁻⁴

➛ V = 2×10³

➛ V = 2×1000

➛ V = 2000 volts.
