The sun's apparent motion across the sky from east to west daily is due to the
a) rotation of the sun.
b) rotation of the earth.
c) orbit of the earth around the sun.
d) orbit of the sun around the earth.

electrical potential energy =0.072 j

explanation:

electrical potential energy is given by

u= q δv

q= charge=6 c

δv= potential difference and is given by

δv= e d

e= electric field

d= distance=5 mm=0.005 m

δv=2.4 (0.005)=0.012 v

now electric potential energy= u= q δv

u=6 (0.012)

u=0.072 j
