Caloulate the electric potensial due to the two partidles at the midpoint between them. Find the magnitude and direction of the electric field there Potential: Magnitude of field 100 1583267 N C 90 Direction of field Toward one of the O protons O Another direction O undetermined

Explanation / Answer

a)

Potential due to both charges at the midpoint :

V = 2*k*q/r

= 2*9*10^9*(1.6*10^-19)/(853*10^-9/2)

= 6.75*10^-3 V <----- answer

b)

Magnitude of field :

E = 0 <----- answer (as both fields due to each charge will cancel each other out )

c)

As electric field is 0 , so the dircetion is undetermined
