Answer:
C. is always perpendicular to the surface of the conductor
Explanation:
On a charged conductor , electric charge is uniformly distributed on its surface . The lines of forces are also uniformly distributed on all directions . They repel each other so they emerge perpendicular to the surface so that they do nor cut each other and at the same time they remain at maximum distance from each other.
The answer to your problem is 15
Answer:
It would become a different element.
Explanation:
When you change the number of protons i.e, add a proton in the nucleus of an atom, you will change the atom from one element to a different element and also positive charge of the atom also increased by 1.
For example, adding a proton to the nucleus of an atom of hydrogen creates an atom of helium.
So, we conclude that by adding a proton the atom will change from one element to another element.
Answer:
The time is 2.8 ms.
Explanation:
Given that,
Capacitor = 0.12 μF
Resistance = 10 kohm
Voltage = 12 V
Charge Q = 0.9 Q₀
We need to calculate the time constant
Using formula of time constant
Put the value into the formula
We need to calculate the time
Using formula of time
Put the value into the formula
Hence, The time is 2.8 ms.
