Experimenter a Uses a Test Charge Q₀ and Experimenter B

Experimenter A uses a test charge q₀ and experimenter B uses a test charge 2q₀ to measure an electric field produced by stationary charges.A finds a field that is:

A) the same as the field found by B
B) greater than the field found by B
C) less than the field found by B
D) either greater or less than the field found by B, depending on the masses of the test charges
E) either greater or less than the field found by B, depending on the accelerations of the test charges
