What is the change in the electrical potential energy in a lightning bolt
if 35 C of charge travels to the ground from a cloud 2.0 km above the
ground in the direction of the field? Assume the electric field is uniform
and has a magnitude of 1.0 × 10° N/C.

Explanation:

Given Data,

Amount of charge transferred to the ground by the lightening bolt, q = 35 C

Amount of charge transferred to the ground by the lightening bolt, q = 35 C

Amount of charge transferred to the ground by the lightening bolt, q = 35 C Distance between the cloud and the ground, d

Amount of charge transferred to the ground by the lightening bolt, q = 35 C Distance between the cloud and the ground, d = 2.0 km = 2000 m

Amount of charge transferred to the ground by the lightening bolt, q = 35 C Distance between the cloud and the ground, d = 2.0 km = 2000 m

Amount of charge transferred to the ground by the lightening bolt, q = 35 C Distance between the cloud and the ground, d = 2.0 km = 2000 m Magnitude of electric field, E = 1.0 × 10⁶ N/C

Now, finding PE(∆U) in lightning bolt,

ΔU = -q×E×dΔU = −35

C × 1.0 × 10⁶

N/C × 2000 m

ΔU = −7.0×10¹⁰ J
