Solved in 3 steps
- A negative charge Q equals -10 muC moves to the right in a uniform electric field if you electron gains 80 muJ of electric potential energy after moving 15 cm give the magnitude and direction of the electric fieldAccording to the sketch, what can be said about the charges? Potential is zero along this solid line Charges These thick solid curves are equipotential surfaces The two charges have opposite signs and equal magnitudes Nothing can be said about the charges The two charges have opposite signs and different magnitudes The two charges have the same sign and equal magnitudes The two charges have the same sign but different magnitudesElectric field lines and equipotential lines are always a) parallel, b) perpendicular, or c) at an angle that depends on the strength of the field.
- Sketch the electric field lines and equipotential lines between two unlike, static point charges of the same magnitude.using no mathematics, explain the physical mechanism by which bound surface charge arises in a dielectric material in an external electric field – how does it come about, what does it ‘look’ like?Elaborate on the way in which the polar character of water molecules helps to explain water’s relatively large dielectric constant.
