What is the total capacitance when three capacitors, C1, C2 and C3 are connected in parallel?
a) C1/(C2+C3)
b) C1+C2+C3
c) C2/(C1+C3)
d) 1/C1+1/C2+1/C3

Text Solution

Verified by Experts

Given, `theta = 53^0
Therefore, `cos 53^0 = 3/5
`sec^2 theta = 25/9`
and ` tan theta = 4/3`
Suppose the ball lands on ninth bench
`:. y=(n-1)1……….i.`
[ ball starting point 1 m above ground ]

Again ` y= x tan theta = ((gx^2 sec^2 theta)/(2u^2)) `
`rarr y= (110+y) (4/3) - (10(110+y)^2(25/9))/(2xx(35)^2)`
`x= 100+n-1=100+y[Using i. ]`
`=440/3+4/3 y (250(100+y)^2)/(18xx(35)^2)`
`440/3+4/3 y (250*110+y)^2)/(18xx35^2)`
From the equation, y cane calculatd as
y=5 ltbr. `rarr n-1 = 5`
`rarr n=6` ltbr. The ball will drop in sixth bench.
