1. ) –4. 00 µC charge lies 20. 0 cm to the right of a 2. 00 µC charge on the x-axis. What is the force on the 2. 00 µC charge? Show solution

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 .

truck y has a greater velocity than truck x.

i think it would be 5

the right answer is 0.3 meters per second
