Let e be the charge of the electron.
Then F1 + F2 = 0
F1 = K (-1.5) * (-e) /r1^2
F2 = K (15) * (-e) /r2^2
(-1.5) * /r1^2 + (15) /r2^2 = 0
-1 /r1^2 + (10) /r2^2 = 0
[r2/r1]^2 = 10
[R2/r1] = ± 3.162
r2 = ± 3.162 r1.
Given r1 + r2 = √ [1^2 + 0.5^2] = 1.1180-----1
Also tan θ = 0.5 => θ = 26.57°
====================================
Substituting r2 = 3.162 r1 in 1
4.162 r1=1.1180
r1 = 0.2686 m
x coordinate = r1 cos θ = 0.2403 m
y coordinate = r1 sin θ = 0.1201m
===================================
Substituting r2 = - 3.162 r1 in 1
-2.162 r1=1.1180
r1 = -0.5171m
x coordinate = r1 cos θ = -0.4625m
y coordinate = r1 sin θ = -0.2313m
===============================
Answer:
0.04658 m from the nut
Explanation:
Recall that torque is defined as the vector product of force (F) times distance (d). Then, given that the force is applied perpendicular to the wrench, gives the sine of the angle (90 degrees) equal to 1, simplifying the calculation which consists basically on solving for d in the equation:
2.25 N*m = 48.3 N * d
d = 2.25 /48.3 m ≈ 0.04658 m
Answer:
Cells
Explanation:
Non-living, it's atoms, but the smallest unit component that all living beings must have is the cell. In fact some living things can be just one cell. Every living being comes from cells, is made up of one or more cells, and cannot be considered a living organism without at least one.
Answer:
Explanation:
The electric force exerted on the electron is given by:
where
is the magnitude of the electron charge
E = 40000 V/m is the electric field
Substituting,
By comparison, the gravitational force exerted on the electron is:
where
is the mass of the electron
g = 9.8 m/s^2 is the acceleration due to gravity
Substituting,
