Two capacitors of `2muF` and `3muF` are charged to `150 V` and `120 V`, respectively. The plates of capacitor are connected as shown in the figure. An uncharged capacitor of capacity `1.5muF` falls to the free end of the wire. Then

A

chargeg on `1.5muF` capacitor is `180 muF`

B

charge on `2muF `capacitor is `120muF`

C

positive chasrge flows through A from right to left

D

positive charge flows through A from left to right

Text Solution

Verified by Experts

The correct Answer is:
A, B, D

Let `(+q)muC` charge flows in the closed loop in clockwise direction. Then final charge on different capatiors we as shown in figure.
Now, applying Kirchoff's loop law
`(360-q)/3+(300-q)/2=q/1.5`
Solving the abvoe equation we get
`q=180muC`
