Two charged particles, with charges q1 = q and q2 = 4q are located at a distance d = 2cm apart on the x axis A third charged particle, with charge q3 = q is placed on the x axis such that the magnitude of the force that charge 1 exerts on charge 3 is equal to the force that charge 2 exerts on charge 3. Find the position of charge 3 when q = 10n C
Answer:
0.667 cm
Explanation:
|F_1on3| = |F_2on3|
k×q1×q3/x^2 = k×q2×q3/(d-x)^2
q1/x^2 = q2/(d-x)^2
(d-x)^2/x^2 = q2/q1
(d-x)/x = sqrt(q2/q1)
(2 - x)/x = sqrt(4×q/q)
(2 - x)/x = 2
2 - x = 2x
2 = 3x
x = 2/3
x= 0.667 cm

A constant current source supplies a electric current of 200 mA to a load of 2kΩ. When the load changed to 50Ω, the load current will be
8A
9mA
700mA
12A
Answer:
700ma
Explanation:
all u do is have to add them up.
Ohm's law allows us to calculate the result for the value of the current when we change the resistance of the circuit:
The current is: i = 8 A
Ohm's law establishes that voltage is proportional to current and we call the constant of proportionality resistance in a circuit.
V = i R
Where V is the voltage, i the current and R the resistance of the circuit.
They indicate that the source supplies a current of i = 200 mA = 0.200 A at a load of R = 2 kΩ = 2 10³ Ω
Let's find the source voltage.
V = 0.200 2 10³
v = 400 V
Now with this voltage let's find the current for the new load of R = 50 Ω
i = V / R
i = 400/50
i = 8 A
In conclusion using Ohm's law we can calculate the result for the value of the current when we change the resistance of the circuit is:
The current is: i = 8 A

In a 1953 experiment a rocket sled went from 284 m/s to rest within 178 m. If the test subject, John Stapp, had a mass of 84.0 kg: a) what is the amount of Work done to stop the John Stapp? b) how much Force was applied to John Stapp?
Oberon is a moon of Uranus. It has a mass of 3.01 x 1021 kg and is 761.4 km away from Uranus. If the force of gravity
of Uranus is pulling 3.00 x 1025 N on Oberon, what is the mass of Uranus? (6 points)
Answer:
acc to formula= F= G m1m2/rsq
mass of Uranus= F×r sq/G×m
M=3.00×10^25×761.4×761.4×10^6/6.67×10^ -11×3.01×10^21
=3×10^25-8×7614×7614/667×301×10^-2-11+21-2
=173918988×10^11/200767
=866×10^11(approx)
[O.04H]The table below shows the use of some energy production methods over time.
Type of energy Average energy used annually in the past (in million tons) Average energy used annually at present (in million tons) Average energy most likely to be used annually in the future (in million tons)
Oil 200 4000 300
Gas 100 2500 700
Coal 1000 2500 1500
Wind 0.1 50 2000
Hydropower 0.7 60 150
