Answer True or False to each case. Coulomb's law states that the force between static charges Q1 and Q2
is proportional to Q1 Q2.
is proportional to the total charge Q1+Q2.
is K Q1Q2/r where K is a universal constant.
is proportional to 1/r2.
is a force of attraction.
k Q1 Q2 / r^2
note r^2 not r
so
1. yes
2 no
3 no
4 yes if you mean 1/r^2
5 not necessarily, Like charges repel.

True.
False.
True.
True.
It could be either. Depending on the charges, it could be a force of attraction or repulsion. What a shocking situation!
True: Coulomb's law states that the force between static charges Q1 and Q2 is proportional to Q1 Q2.
False: Coulomb's law is not directly proportional to the total charge Q1+Q2. It is only proportional to the individual charges Q1 and Q2.
True: Coulomb's law states that the force between static charges Q1 and Q2 is given by F = K Q1Q2/r, where K is a universal constant.
True: Coulomb's law states that the force between static charges Q1 and Q2 is inversely proportional to the square of the separation distance r, i.e., 1/r^2.
False: Whether Coulomb's law results in a force of attraction or repulsion depends on the signs of charges Q1 and Q2. Like charges (same sign) repel each other, while opposite charges (different signs) attract each other.
Case 1: True. According to Coulomb's law, the force between static charges Q1 and Q2 is indeed proportional to the product of their charges, Q1 and Q2.
Case 2: False. The force between static charges Q1 and Q2 is not directly proportional to the total charge Q1+Q2. Instead, it is solely determined by the charges of the individual particles, Q1 and Q2.
Case 3: True. According to Coulomb's law, the force between static charges Q1 and Q2 is given by the equation F = K(Q1Q2/r), where K is a universal constant.
Case 4: True. Coulomb's law states that the force between static charges Q1 and Q2 is inversely proportional to the square of the distance, 1/r^2. So, as the distance between the charges increases, the force decreases.
Case 5: False. The force between static charges Q1 and Q2 can be either attractive or repulsive depending on the charges. If the charges have opposite signs (one positive and the other negative), it results in an attractive force. However, if the charges have the same sign (both positive or both negative), it results in a repulsive force.
