Answer:
The electric field generated by a point charge is given by:
where
is the Coulomb's constant
Q is the charge
r is the distance from the charge
We want to know the net electric field at the midpoint between the two charges, so at a distance of r=5.0 cm=0.05 m from each of them.
Let's calculate first the electric field generated by the positive charge at that point:
where the positive sign means its direction is away from the charge.
while the electric field generated by the negative charge is:
where the negative sign means its direction is toward the charge.
If we assume that the positive charge is on the left and the negative charge is on the right, we see that E1 is directed to the right, and E2 is directed to the right as well. This means that the net electric field at the midpoint between the two charges is just the sum of the two fields:

Answer:
The slope of the capital allocation line formed with the risky asset and the risk-free asset is approximately 0.5
Step-by-step explanation:
given data
invested = $1000
rate of return = 16%
standard deviation = 20%
rate of return = 6%
to find out
The slope of the capital allocation line
solution
we know here rate of return equation for find slope of line that is
R1 = R2 + σ × slope of line .............1
here R is rate of return and and σ is standard deviation
put here all value in equation 1
16 = 6 + 20 × slope of line
20 × slope of line = 10
slope of line = 0.5
so
The slope of the capital allocation line formed with the risky asset and the risk-free asset is approximately 0.5
Answer:
Step-by-step explanation:
Triangle HIJ is a right angle triangle.
From the given right angle triangle
IJ represents the hypotenuse of the right angle triangle.
With ∠J as the reference angle,
HJ represents the adjacent side of the right angle triangle.
HI represents the opposite side of the right angle triangle.
To determine IJ, we would apply Sine trigonometric ratio. It is expressed as
Sin θ = opposite side/hypotenuse. Therefore,
Sin 54 = 7/IJ
0.8090 = 7/IJ
IJ = 7/0.8090
IJ = 8.7 to the nearest tenth
