Ep = mgh = 47.0 J
m = 0.8 kg
g = 9.81 m/s2 (average)
h = Ep / mg = 47 J / 0.8 kg * 9.81 m/s2 = 5.989 m
Answer:
a)v= 675V
b) v=-675V
c)v=-450V
Explanation:
Formula: V = k*sum(qi/ri)
Given:
q1 = +6.00nC --> R1 = 2.00cm
q2 = -9.00nC --> R2 = 4.00cm
(a) r = 0. So, inside both shells
V=675V
(b) r = 4.00cm. So, This point is outside of shell 1 but inside shell 2.
V=-675V
(c) r = 6.00cm. So, This point out of both shells.
Distance is how far something moves in a specific amount of time.
