PartA Does the electric field point toward or away from the charge? Electric field points away from the charge Electric field points toward the charge Submit Part B What is the magnitude of the electric field 0.41 m from the charge? Express your answer to two significant figures and include the appropriate units EValue UnitsExplanation / Answer
A) Electric field points away from the charge
Electric field originates from positive charge and are directed towards negative charge so electric field will be away from the charge
B) 2.5*105 Newton/coulomb
Electric field magnitude=k*q/r2
=8.99*109*4.7*10-6/(0.41*0.41)
=251356.33 Newton/coulomb
=2.5*105 Newton/coulomb(2 signifant digits)
