Answer:
The value of third charge is 0.8μC.
Explanation:
Given that.
Magnitude of net force=4.444 N
According to figure,
Suppose, First charge = 2.4 μC
Second charge = 6.2 μC
Distance r₁ = 9.8 cm
Distance r₂ = 2.1 cm
We need to calculate the value of r
Using Pythagorean theorem
Put the value into the formula
We need to calculate the force
Using formula of force
Force F₁₂,
Force F₂₃,
We need to calculate the value of third charge
Hence, The value of third charge is 0.8μC.
Answer: 33.32 s
Explanation: gravity =9.8m/s2 which means that 3.4mx9.8m/s2=33.32s
I hope this helped ! Sorry if it’s wrong :)
False.
It is important to know what is around you when making decisions
To solve the problem, start by applying the concepts related to current in an RL circuit. The current is defined exponentially and using Ohm's law we can put the initial current in terms of the voltage and resistance. Consecutively with the calculated time constant we can find the respective inductance. For the second part we will apply the electrical potential energy connectors to find the amount of stored energy.
PART A)
Inductance can be defined then,
PART B) Now the energy is given under the terms:
Therefore the energy stored in the coil at this same moment is 0.0002727J
