A 5 mu F capacitor is charged fully by a 220 V supply. It is then disconnected from the supply and is connected in series to another uncharged 2.5 mu F capacitor . If the energy change during the charge redistribution is X/100 J then value of X to the nearest interger is ________.

The plates of a parallel plate capacitor have on area of 90 cm^(2) each and are separated by 2.5 mm . The capacitor is charged to 400 V. How much electrostatic energy is stored in it ? How much when it is filled with a dielectric medium K = 3 and then charged ? If it is first charged as an air capacitor and then filled with th dielectric, then ?

In a row of 24 boys, when Ajay was shifted by 4 places towards left, he became 8th from the left end. What was his earlier position from the right end of the row? 1) 12th 2) 13th 3) 14th 4) 15th 5) None of these

Read the following information carefully to answer the questions that follow. In a survey of 25 students, it was found that 15 have taken Mathematics. 12 have taken Physics and 11 taken Chemistry, 5 have taken Mathematics and Chemistry, 9 have taken Mathematics and Physics, 4 have taken Physics and Chemistry and 3 have taken all the three subjects. The number of students who have taken only Physics, is (a)2 (b)3 (c)5 (d)6

The surface density of charge on the surface of a charged conductor in the air is 26.5 muCm^(-2) . The the outward force per unit area of the charged conductor is (epsilon_0=8.85xx10^-12C^2N^-1m^-2)

The average of twelve numbers is 55.5. The average of the first four numbers is 53.4 and that of the next four numbers is 54.6. The 10th number is greater than the 9th number by 3 but lesser than the 11th and 12th numbers by 2 and 3, respectively. What is the average of the 10th and the 12th numbers? बारह संख्याओं का औसत 55.5 है | पहली चार संख्याओं का औसत 53.4 है तथा अगली चार संख्याओं का औसत 54.6 है | 10वीं संख्या 9वीं संख्या से 3 अधिक है लेकिन 11वीं और 12वीं संख्याओं से क्रमशः 2 और 3 कम है | 10वीं और 12वीं संख्याओं का औसत ज्ञात करें |

The average of twelve numbers is 45.5. The average of the first four numbers is 41.5 and that of the next five numbers is 48. The 10th number is 4 more than the 11th number and 9 more than the 12th number. What is the average of the 10th and 12th numbers? बारह संख्याओं का औसत 45.5 है | पहली चार संख्याओं का औसत 41.5 है तथा अगली पाँच संख्याओं का औसत 48 है | 10वीं संख्या, 11वीं संख्या से 4 अधिक तथा 12वीं संख्या से 9 अधिक है | 10वीं तथा 12वीं संख्याओं का औसत कितना है ?
