4. What is the unit of surface charge density in the SI unit? a) C b) C/m c) C/m2 d) C/m3
Answer: c Explanation: Surface charge density means how much charge is stored in the unit surface area of a conductor. So, it’s unit will be=theunitofthechargetheunitofarea. In SI the unit of charge is Coulomb and the unit of area is m2. Therefore the required unit will be C/m2.
