Answer:
1. False
2. True
3. True
Explanation:
1- False —> The relation between electric potential and electric field is given such that
![-\int\limits^a_b \vec{E}d\vec{l} = V_{ab}](https://tex.z-dn.net/?f=-%5Cint%5Climits%5Ea_b%20%5Cvec%7BE%7Dd%5Cvec%7Bl%7D%20%3D%20V_%7Bab%7D)
Therefore, for a uniform E field, electric potential is linearly proportional to the distance.
2- True —> The electric field lines always cross the equipotential lines perpendicularly.
3- True —> In order to be a potential difference, one source of electric field is enough. The electric potential will decrease radially according to the following formula:
![V = \frac{1}{4\pi\epsilon_0}\frac{q}{r^2}](https://tex.z-dn.net/?f=V%20%3D%20%5Cfrac%7B1%7D%7B4%5Cpi%5Cepsilon_0%7D%5Cfrac%7Bq%7D%7Br%5E2%7D)
There is no test charge in the formula, only the source charge. Even when there is no test charge, the potential difference between points in space can exist.
Answer:
Because it is said that the earth rotates and revolves around the sun and moon so it is impossible for the earth not to be spinning.
