Turn on your headlights, be careful, stay off your cellphone, pay attention to the car in front of you.
Resistance=12Ω
Voltage=24v
Current=voltage/resistance
Current=24/12= 2A
Answer is option C
Explanation:
The given data is as follows.
q = 6.0 nC =
inner radius (r) = 1.0 cm = 0.01 m (as 1 cm = 100 m)
So, there will be same charge on the inner surface as the charge enclosed with an opposite sign.
Formula to calculate the charge density is as follows.
.......... (1)
Since, area of the sphere is as follows.
A = ........... (2)
Hence, substituting equation (2) in equation (1) as follows.
=
=
or, = 4.77
Thus, we can conclude that the resulting charge density on the inner surface of the conducting sphere is 4.77 .
Answer:
The standard quantity with which we carry out the measurement of any physical quantity of the same kind is called a unit.
