What is the electric potential (voltage) 30.0 cm from a -9.7 u point charge?

-- 270,000 V
- none
-270,000 V
- 291,000 V
-291,000 v

if the person is shown to have +90n, then ans is -10n.

if the person is shown to have -90n, then ans is +10n.

this would be about 43%

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
