When capacitors are connected in series ___________ remains the same.
a) Voltage across each capacitor
b) Charge
c) Capacitance
d) Resistance

Explanation

Let the velocity of car be u, whne the ball is thrown.
Initial velocity of car = Horizontal velocity of ball.
Distnce travelled by ball B,
`S_b= ut` (in horizontal direction)
Extra distance travelled by car
`=S_c-S_b`
`=1/2 at^2`

Ball can be considered asd a projectile having
`theta= 90^0`
`t= (2u sin theta)/6
`=(2xx9.8)/9.8= 2 sec`
`:. S_c-S_b= 1/2 at^2 = 1/2 (1) 2^2= 2m`
Hence, the ball will drop 2 m behind the boy.
