Answer:
The value of charge q₃ is 40.46 μC.
Explanation:
Given that.
Magnitude of net force 
Suppose a point charge q₁ = -3 μC is located at the origin of a co-ordinate system. Another point charge q₂ = 7.7 μC is located along the x-axis at a distance x₂ = 8.2 cm from q₁. Charge q₂ is displaced a distance y₂ = 3.1 cm in the positive y-direction.
We need to calculate the distance
Using Pythagorean theorem
Put the value into the formula
We need to calculate the magnitude of the charge q₃
Using formula of net force
Put the value into the formula
Hence, The value of charge q₃ is 40.46 μC.
The charge on each of the equally charged drops of hairspray willl be 7 × 10 ⁻¹³ C
<h3>What is Columb's law?</h3>
The force of attraction between two charges, according to Coulomb's law, is directly proportional to the product of the charges and inversely proportional to the square of the distance between them.
Similar charges repel each other, whereas charges that are opposed attract each other.
Given data;
Electric force,F = 9 × 10 ⁻⁹ N
Distance between charges,d = 7 × 10⁻⁴ m
Chrge,q₁ = q₂ =q C
From Columb's law;
Hence the charge on each of the equally charged drops of hairspray willl be 7 × 10 ⁻¹³ C

The forces acting on your mom while cooking is Air resistance and the force of friction
<u>Explanation:</u>
<u>1. Air resistance:</u>
- In simple words, Air resistance can be stated as the type of friction between the air and the other materials.
- In this scenario, there will be an air resistance and the air hits the mom while cooking via the doors or windows
<u>2. The force of friction:</u>
- In simple words, friction can be stated as, the resistance that one surface or object encounters when moving over another.
- While cooking the food mom would experience the friction since friction is the transfer of heat, and cooking is the process of receiving that heat.
Answer:
c. gravitational attraction between the sun and earth
