place the charge q= 2.10-5C at the origin O of the Oxy-axis system. consider two points A(6;0) and B(3;4) on the axes with unit of measurement in cm. choose the potential origin at infinity. Calculate the work done by the electric field when moving the charge q=-1uc from A to B

The electric potential v is constant everywhere within a certain region of space. which statement below is true? the choices are: the electric field is also constant (but not zero) within the region. a charged particle placed within the region will experience an electric force. the electric field is zero everywhere within the region. the electric field varies from place to place within the region.
