|
Answer» Solution :` C=(Ain _0)/( d) ` ` (##MOT_CON_JEE_PHY_C25_SLV_030_S01.png" width="80%"> ` (1)/(C_(EQ) ) =(1)/(c) +(2)/(3C) =(5)/( 3C) ` ` rArr "" C_(eq) =(3C)/( 5) =(3Ain _0)/( 5d) ` Alternative method : ` C=(Q)/( V) = (X+y)/(V_(AB) ) ` ` C= (Q)/(V)= (x+y)/( V_( AB) ) ` ` (##MOT_CON_JEE_PHY_C25_SLV_030_S02.png" width="80%"> Potential of 1 and 4 is same ` (y)/( Ain _0) =( 2X)/( A in _0) "" y =2x` ` V= ((2Y +x)/( Ain _0)) d ` `C= ( (x+ 2x )A in _0)/( (5x )d) =( 3A in _0) /( 5d) ` |
