Which of the following statements regarding charge is most accurate?
One type of charge acts like an invisible fluid that can move between objects.
Objects with like charges repel, while objects with opposite charges attract.
Objects with like charges attract, and objects with opposite charges also attract.
Static electric forces, like gravity forces, always attract and never repel.

Two identical metal blocks are in contact side-by-side. A positively charged rod moves near the left
block. Which of the following most accurately shows the resulting distribution of charge throughout the
metal blocks?
Question

Which of the following is an accurate example of charging by induction?
A student brings a charged rod near a block of metal. The student taps the block of metal with a
hand and then removes the charged rod.
A student rubs a glass rod with a silk cloth.
A student places a neutral metal box in contact with a positively charged metal box.
A student places a positively charged metal box in contact with a negatively charged metal box.
Question

Particle A has a net charge of -5 C. Particle B has a net charge of +10 C. Which of the following is
the largest force?
The force of particle A on B
The force of particle B on A
They apply the same force on each other.
More information is needed (the distance between the particles needs to be known).
Explanation / Answer
Q 11 of 20
Objects with like charges repel, while objects with opposite charges attract.
This is according to the fundamental properties of electrostatic charges.
Q 12 of 20
Protons
Protons always carries a positive charge
Q 13 of 20
Option D is correct (last option)
When a positively charged rod moves near the left of the block, it attracts or pulls negative cherge of the block.
Q 14 of 20
A student rubs a glass rod with a silk cloth.
When silk is rubbed on a glass rod, an electrostatic charge is generated by induction in a phenomenon known as the triboelectric effect.
Q 15 of 20
The force of particle B on A
Because the magnitude of electroctatic charge of B (+10 C.) is more than the charge of A (-5 C).
