Charge above a conducting plane a positive point charge q ia fixed at the point (0,0,z0) above a grounded conducting plane at z = 0. (a) what is the total charge induced on the plane? (b) determine the radius of the circle centered at the origin in the xy plane which enclose half of the total charge induced on the plane. (c) determine the force on the charge. (d) determine the energy in the electric field. how does this compare with the energy of two charges +q and −q at a separation of 2z0.

gpe = mass x gravity constant x height or… gpe = mgh

where… mass: measured in kilograms (kg)

gravity: gravity constant on earth = 10.00 m/s2

height: measured in meters (m)

gpe: measured in joules (j) or kilojoules (kj)

how do you solve gpe?

gravitational potential energy (gpe) is the energy an object has because of its position above the. ground.

gpe = mass x gravity constant x height or… gpe = mgh.
