two point charges are seperated by 10 cm and have charges of +2 uC and -2 uC , respectively. what is the electric field at a point 4 cm from the +2 uC charge and on a line connecting the two charges? two point charges are seperated by 10 cm and have charges of +2 uC and -2 uC , respectively. what is the electric field at a point 4 cm from the +2 uC charge and on a line connecting the two charges? two point charges are seperated by 10 cm and have charges of +2 uC and -2 uC , respectively. what is the electric field at a point 4 cm from the +2 uC charge and on a line connecting the two charges?Explanation / Answer
Consedering test charge in between given two charges
Electric field due to +2uC
kq/r2 = 9*109*2*10-6/0.042 = 11.25*106 N/C
Electric field due to -2uC
kq/r2 = 9*109*2*10-6/0.062 = 5*106 N/C
Both act along same direction so Enet = 16.25*106 N/C
