Answer:
P = 6*5 = 30 [kg*m/s]
Explanation:
in order to solve this problem, we must remember that linear momentum is defined as the product of mass by Velocity. This way you can calculate the momentum using the following equation.
P = m*v
where:
P = lineal momentum [kg*m/s]
m = mass = 6 [kg]
v = velocity = 5 [m/s]
P = m*v
P = 6*5 = 30 [kg*m/s]

Answer:
Explanation:
From the question we are told that
Distance b/w Q mid point and P is given as x
Generally the equation for magnitude of the electric field at the point P is given as
where
Therefore
Therefore equation for magnitude of the electric field at the point P is
Answer: the ball will have a charge of 8x10^8C when we remove 5x10^27 electrons.
Explanation:
If the sphere is neutral, then the charge of the sphere is 0C
Now, when we remove an electron (-1.6*10^-19 C) we are subtracting a negative number, so the new charge of the sphere is: 1.6*10^-19 C
Now, for N removed electrons, the charge of the sphere is:
N*1.6*10^-19 C
We want to find the number N when:
N*1.6*10^-19 C = 8.0x 10^8 C
N = (8.0/1.6)x10^(8 + 19) = 5x10^27 electrons.
