Answer:
Force,
Explanation:
There are two positive charges, 2 C and 5 C, separated by a distance of 20 cm in a vacuum. What is the value of the modulus of the electrostatic force between them?
We have,
Charge on object 1, q₁ = 2 C
Charge on object 2, q₂ = 5 C
Distance between charges, r = 20 cm = 0.02 m
The electric force between two charges is given by the formula as follows :
Plugging all the values we get :
So, the electric force between two charges is .
Answer:
The density is
Explanation:
From the question we are told
The radius of the cylinder is
The length of the cylinder is
The density of the glucose is
The depth is
The net force on the string is
The net force on the string is mathematically represented as
Here is the force due to the weight of the cylinder
Which mathematically evaluated as
Where is the volume of liquid displaced which is equal to the volume of the cylinder which is mathematically represented as
=>
is the buoyant force acting on the cylinder due to the glucose
So substituting into formula for
During convection of air currents, cool air sinks. <em>(b)</em>
