An 8 kg desk and a 2 kg textbook are both pushed with the same force of 5 N. Which one is going to have the higher acceleration and why? Explain using Newton's 2nd law.

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 .
