5) A capacitor is discharged through a 50.0 resistor. The discharge current decreases to 27.0% of its initial value in 1.40 ms .
What is the value of the capacitor?
= Nm2/CExplanation / Answer
electric flux is,
flux = [Eout - Ein]A
= {[350x+140] - [350(0)+140]}A
= {[350(0.013)+140] - [140]}*[0.013]^2
=7.6895e-4 Nm2/C
=7.7e-4 Nm2/C
