An object moving in a circular path has centripetal acceleration. <em>(A)</em>
It's true IF ' m ' stands for mass and ' v ' stands for acceleration. Otherwise it's false.
Answer:
Block A will have a final charge of 3.5nC.
Explanation:
This is because at the point of contact with Block B, which is electrically positive, the electrons in Block A will be attracted to the excess 'unpaired' protons in block B. Hence, the electrons will flow into Block B causing unpaired protons to remain in Block A.
This process is called Charging by Conduction.
This charging process will continue until the charges are evenly distributed between both objects.
In case you're wondering, "<em>how's all this possible within a few seconds</em>?", remember that electrons travel very fast and so, this process is a rather rapid one.
The period of the wave would be halved
Using Fleming’s left hand rule,
The magnetic force on the electron will be west. Example: If it is dropped above the equator in Africa, the electron will head towards North America.
