A charged cork ball of mass 1.50 is suspended on a light string in the presence of a uniform electric field as shown in Figure. When = (2.50+ 6.00)×105 /, the ball is in equilibrium at =35.08. Find (a) the charge on the ball (b) the tension in the string.

think its the third option

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.
