Question 1.
What is Coulomb's Law essentially about?
Show hintHide hint
Think about what charges do to each other.
Question 2.
Is the force directly or inversely proportional to the distance between the charges?
Show hintHide hint
Recall how distance affects the force.
3Question 3.
What is the equation for Coulomb's Law?
Show hintHide hint
Remember what variables are involved in the formula.
4Question 4.
True or False: The force between two charges increases as the distance between them increases.
Show hintHide hint
Think about the relationship of force and distance.
Question 5.
Two charges of +1 µC and -2 µC are placed 0.3 m apart. Calculate the force exerted on each charge.
Show hintHide hint
Consider the nature of the charges (attractive or repulsive).
Question 6.
In a scenario with four charges arranged in a line, where two are positive and two negative, calculate the net force acting on the middle charge, considering their respective distances.
