Answer:
P = 400248 [Pa]
Explanation:
We can calculate the hydrostatic pressure exerted by a column of liquid by means of the following equation.
where:
Ro = density = 1020 [kg/m³]
g = gravity acceleration = 9.81 [m/s²]
h = depth = 40 [m]
Therefore:
Answer:
The new force between the charges becomes double of the initial force.
Explanation:
The force acting between charge particles is given by :
k is electrostatic constant
r is distance between charges
If one of the charges are doubled, then, q₁ = 2q₁
The new force becomes,
So, the new force between the charges becomes double of the initial force.
