Answer:
The forces experienced by the middle particle are attractive, and the net force will remain the same (0) if and only if the distances of the sides particles to the middle particle are the same.
Explanation:
In example 20.3 the forces experienced by the middle particle are repulsive because all the particles are positive, for the case in which the particles on the sides are replaced for negative charge particles the forces experienced by the middle particle are attractive. Regarding the net force, because we don't know the distances we can not give a definitive answer, what we can say is that if the distances from the middle particle to the sides particles are the same the net force is zero for both cases (remain unchanged).
Answer:
Charging by induction
Explanation:
There are four methods of charging. They are as follows :
- Charging by friction
- Charging by induction
- Charging by conduction
- Grounding
Charging by induction is the transfer of charges when there is no direct contact between the materials. The law of conservation of charge also follows in the process of charging by induction.
Answer: 0.1 Amps
Explanation:
Given that,
heat released (H) = 4800 J
Time taken (T) = 8 minutes
Since the unit of time is seconds, convert 8 minutes to seconds
(1 minute = 60 seconds
8 minutes = 8 x 60 = 480 seconds)
current in the conductor (I) = ?
The conductor resistance (R) = 1kΩ
Convert kilo-Ohms (kΩ) to ohms (Ω)
(If 1000Ω = 1kΩ
1kΩ = 1000Ω)
Now, apply the formula:
H = I²RT
4800J = I² x 1000Ω x 480 Seconds
4800J = 480000Ω•I²
Divide both sides by 480000Ω
4800J/480000Ω = 480000Ω•I²/ 480000Ω
0.01 = I²
To get the value of I, find the square root of I²
I = √0.01
I = 0.1 Amps
Thus, the current in the conductor is 0.1 Amps
