If200 J of work are required to carty a charged particle betwoen two points with a potential difference of 10 V, the magnitude of the charge on the particle is A. 0.040 C B.12.5 C ?, 20 ? D. cannot be computed unlem the path in given E none of these 7. Two capacitors are identical. They can be conpected in series or in parallel. If you want the smallest equivalent capacitasce for the combination, how ahould you comnect them? A. in series B. in parallel C. either way because both combinations have the same capacitance D. cansot be computed unless the voltage is given E G+(1/Ca) 8.

Explanation / Answer

5) Joule per Coulomb is Volt

correct option is B

6)magnitude of charge = 200/10=20 C

correct option is C

7)For smalledt equivalent capacitance , they should be connected in series.

Correct option is A

8) Due to introduction of dielectric material, electric field becomes weaker

correct option is C
