Answer:
σ =4.180×10^{-9} C/m^2
Explanation:
electric field due to non conducting sheet is
the force acting on the piece of Styrofoam
Eq= mg
⇒E= mg/q
now,
⇒
charge per unit area (in C/m2) on the plastic sheet σ =4.180×10^{-9} C/m^2
Answer: The work done in J is 324
Explanation:
To calculate the amount of work done for an isothermal process is given by the equation:
W = amount of work done = ?
P = pressure = 732 torr = 0.96 atm (760torr =1atm)
= initial volume = 5.68 L
= final volume = 2.35 L
Putting values in above equation, we get:
To convert this into joules, we use the conversion factor:
So,
The positive sign indicates the work is done on the system
Hence, the work done for the given process is 324 J
