Two point charges `q_(1) = 4 mu C` and `q_(2) = 9 mu C` are placed `20 cm` apart. The electric field due to them will be zero on the line joining them at distamce of

Two point charges q_(A)= 3mu C and q_(B) = - 3muC are located 20cm apart in vacuum. What is the electric field at the mid point of the line joining the two charges.

Two point charges q_(A) = 3 mu C and q_(B) = -3 muC are located 20 cm apart in vaccum (a) what is the electric field at the mid point O of the line AB joining the two charges ? (b) If a negative test charge of magnitude 1.5xx10^(-9) C is placed at the point, what is the force experienced by the test charge ?

Two point charges q_(A) = 3 mu C and q_(B) = -3 muC are located 20 cm apart in vaccum (a) what is the electric field at the mid point O of the line AB joining the two charges ? (b) If a negative test charge of magnitude 1.5xx10^(-9) C is placed at the point, what is the force experienced by the test charge ?

Two positive charges of 1mu C and 2 mu C are placed 1 metre apart. The value of electric field in N/C at the middle point of the line joining the charge will be :

Two point charges q_(A) =3 mu c and q_(B)=-3 mu c are located 20 cm apart in a vacuum (a) what is the electric field at the midpoint O of the line AB joining the two charges (b) if a negative test charge of magnitude 1.5 xx 10^(-9) c is placed at this point what is the force experienced by the test charge

The point charges q_(A)=3 muC and q_(B)=-3 muC are located 20 cm apart in vaccum. What is the electric field at the midpoint O of the line AB joining the two charges?
