With the use of electric force formula, the direction and magnitude of the net force exerted on the point charge q3 are 9.9 x N and 66 degrees
ELECTRIC FORCE (F)
F =
Where K = 9 x N/
The distance between and can be calculated by using Pythagoras theorem.
d =
d = 46.7 cm = 0.467 m
For force , substitute all the parameters into the formula above
= (9 x x 3 x 1)/
= 2.7 x /0.218
= 1.24 x N
For force , substitute all the parameters into the formula above
= (9 x x 3 x 4)/
= 1.08 x /0.1089
= 9.92 x N
For force , substitute all the parameters into the formula above
= (9 x x 3 x 2)/
= 5.4 x /0.1089
= 4.96 x N
Summation of forces on Y component will be
= - Sin 45
= 9.92 x - 1.24 x Sin 45
= 9.04 x N
Summation of forces on X component will be
= - Cos 45
= 4.96 x - 1.24 x Sin 45
= 4.08 x N
Net Force =
Net force =
Net force = 9.9 x N
The direction will be
Tan ∅ = /
Tan ∅ = 9.04 x / 4.08 x
Tan ∅ = 2.216
∅ = (2.216)
∅ = 65.7 degrees
Therefore, the direction and magnitude of the net force exerted on the point charge q3 are 9.9 x N and 66 degrees approximately.

mass = 30kg
frictional force = coefficient of friction * (mass * g)
g = 9.8 m/s^2
So:
60N = x * 294 N
x = 60 N / 294 N = 0,2
Answer:
The formula is: weight/mass = gravitational field strength. On Earth the gravitational field strength is 10 N/kg.

Answer:
E=Ur/2E_{0}
Explanation:
Consider a long cylindrical charge distribution of radius R with a uniform charge density rho. (a) Find the electric field at distance r from the axis where r R.
to find the electric point inside the cylinder
r=radius of the cylinder
A=curved surface area of the cylinder
∪=charge density
Q=is the net charge
V=volume of the cylinder
Q=UV
volume of the gaussian cylinder =
Q=U
area A=
Write the expression Gaussian law
∅=∫EdA=Q/..........................1
E_{0} is the permittivity of free space and Eois the electric field
rewriting the equation 1 , we have
EA=Q/E_{0}
substituting for A and also for Volume V in the equation above
E*=U/E_{0}
E=Ur/2E_{0}
