The electric force experienced by a charge of 1.0×10−6C is 1.5×10−3N. N. Fin the magnitude of the electric field at the position of the charge.
Fe=θE,E=Feθ=1.5×10−31.0×10−6=1.5×103N/C
Two point charges qA=3μC and qB=–3μC are located 20 cm apart in vacuum. What is the electric field at the midpoint O of the line AB joining the two charges?
If a negative test charge of magnitude 1.5×10–9C is placed at this point, what is the force experienced by the test charge?
The electric field and force experienced by a test charge placed at origin is 6 x 105 N/C and 18 x 10-4 N. The value of test charge is:
