Electrostatics is the study of:
- AMoving charges
- BStationary charges
- CMagnetic fields
- DElectric circuits
The two types of electric charge are:
- APositive and neutral
- BNegative and neutral
- CPositive and negative
- DNorth and south
Like charges:
- AAttract each other
- BRepel each other
- CHave no effect on each other
- DCombine to form neutral charge
The SI unit of charge is:
- ANewton
- BJoule
- CCoulomb
- DAmpere
When an object loses electrons, it becomes:
- ANegatively charged
- BPositively charged
- CNeutral
- DMagnetized
Materials that allow electric charge to flow freely are called:
- AInsulators
- BConductors
- CSemiconductors
- DResistors
An electroscope is used to:
- AMeasure electric current
- BDetect the presence and sign of electric charge
- CMeasure magnetic field
- DGenerate electricity
The direction of the electric field at a point is the direction of the force on:
- AA negative test charge
- BA positive test charge
- CA neutral particle
- DA magnetic monopole
Electric field lines point:
- ATowards positive charges
- BAway from negative charges
- CAway from positive charges and towards negative charges
- DIn random directions
The SI unit of electric field intensity is:
