Q-5.1

Two parallel-plate capacitors, 7.8 uF each, are connected in parallel to a 45 V battery. One of the capacitors is then squeezed so that its plate separation is halved. Because of the squeezing, (a) how much additional charge is transferred to the capacitors by the battery and (bi what is the increase in the total charge stored on the capacitors? (a) Number n Units v (bl Number n Units v ( b ) Increase in total charge stored on capacitors Initially charge stored by each capacitors is (7.8* 45) = 35 1 UC Each capacitor store 351 UC . After Squeez 7. B UF Capacitor store ( 7.8x 45 ) UC = 35luc . 15. 6/F capacitor store ( 15.6* 45 ) UC = 702 UC . change increased in unsqueezed capacitor is zero Charge increased in squeezed capacitor (702 - 351 ) Mc = 35luc. Increase in total charge stored is ( 0+ 351 ) uc = 351 UC
