## Chapter 15 - Electrostatics - 2

 1. Volt is the unit ofa) Power b) potential differencec) currentd) capacitance
 2. Solid bodies are charged due to transfer ofa) protons b) neutronsc) electronsd) nucleus
 3. Electrostatics is the branch of physics which deals with the chargesa) at rest b) suspendedc) in motiond) neutral particles
 4. If the distance between two charged bodies is much greater as compared to their size, then, the bodies are considered asa) electrons b) neutral pariclesc) atomsd) point charges
 5. The value of electric intensity at a point is 10N/C and charge placed there is 2 coulomb. The force experienced by that charge isa) 22 N b) 12 Nc) 20 Nd) 10 N
 6. The value of eletrostatic constant K isa) 9x 109 Nm2/C2 b) 9 x 109 C2/Nm2c) 9 x 10^-9 Nm2/C2d) 9 x109 N
 7. The potential difference between two points is given by the expressiona) W=V/q b) V=w/qc) V=wqd) W=VQ
 8. Electron volt is the unit ofa) Energy b) Nuclear powerc) potential differenced) power
 9. If the capacitance of a capacitor is 10mewF and potential difference is 2 volts then charge stored isa) 20 Coulombs b) 30 Coulombsc) 20 x 10-6 Coulombsd) 20 x 106 Coulombs
 10. If the two capacitors are each of 2mewF are connected in series comination then their equivalent capacitance will bea) 1mewF b) 2mewFc) 3mewFd) 4mewF
 11. The distance beween two point charges is 10cm if the distance is reduced to 5cm the Coulombs force would becomea) 0.04 N b) 100 Nc) 25 Nd) 4 N
