Metal spheres 1 and 2 are connected by a metal wire. What quantities do spheres 1 and 2 have in common? A. Same potential
B. Same electric field
C. Same charge
D. Both A and B
E. Both A andC 2

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.
