Newton's first Law implies that an object at rest will remain at rest unlss a net force acts on it / TRUE or FALSE?

True

Explanation:

If an object is at rest it will stay at rest unless a force acts on it.

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
