Question

in a certain region of space for uniform electric field has a direction from east to west when a negative charge is placed in this field it experiences a force state the direction of the force​

Answer 1

Answer:

−10−2N

Consider an electric dipole with −q charge at A and +q charge at B, placed along z-axis, such that its dipole moment is in negative z direction.

i.e., Pz=10−7C m

The electric field is along positive direction of z-axis, such that

dzdE=105N C−1m−1

From, F=qdE

=(q×dz)×dzdE=pdzdE

Force experienced by the system in the negative z-direction,

F=p×(−dzdE)=10−7×(−105)=−10−2N.
