A. 1*1011 Nm2C-1
B. 2.1*1011 Nm2C-1
C. 2.1*1010 Nm2C-1
D. 7.1*1011 Nm2C-1
Answer:B
If a 10C charge is placed in a medium having relative permittivity 5.4, what will be the amount of flux coming out of that charge?
A. 1*1011 Nm2C-1 B. 2.1*1011 Nm2C-1 C. 2.1*1010 Nm2C-1 D. 7.1*1011 Nm2C-1
Explanation: Gauss’s Law states that electric flux coming out of a charge is=\(\frac {amount \, of \, charge}{permittivity \, of \, the \, medium}\). In this case, the charge is 1C and permittivity of the medium=5.4*8.85*10-12. Substituting the values, we get the total flux coming out of the charge is 2.1*1011 Nm2C-1.
