An elephant, mass 1100 kg, stands on the ground above a point charge with +3 c of charge that has been buried 0.8 m beneath the ground. how much charge would you need to put on the elephant in order to make it float?

Explanation:

k = Coulomb constant =

g = Acceleration due to gravity = 9.81 m/s²

r = Distance between charge = 0.8 m

m = Mass of elephant = 1100 kg

= Mass on first charge = 3 C

The electrostatic force will balance the weight of the elephant as the energy in the system is conserved

The charge on the other particle is

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 .

speed

ratio of distance traveled to time interval

net force

vector sum of forces on object

object

source of diverging light rays either luminous or illuminated
