0 m/s
b
19.3 m/[forward
с
10.5 m/s forward
d
17.8 m/s forward

audio tape

explanation:

not too sure thinking it will always be directed towards the centre of the earth. could be wrong not sure

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
