Question

Calcule o potencial elétrico num ponto situado a 2,5.10^5 cm de uma carga q= 50 pC.​

Answer 1

U=K⁰.Q/d

U=?

K⁰=9×10^9

Q=50×10^-12

d=2,5×10^3 1m------100cm

x---------2,5×10^5

x=2,5×10^5/10^2

x=2,5×10^3 m

U=(9×10^9).(50×10^-12)/(2,5×10^3)

U=(450×10^-3)/(2,5×10^3)

U=180×10^-6

U=1,8×10^4 V
