Which among the following expressions relate charge, voltage and capacitance of a capacitor?
a) Q=C/V
b) Q=V/C
c) Q=CV
d) C=Q2V

Explanation

The velocity of the food packet at the time of rrelease is u and is horizontal. The vertical velocity at the time of release is zero
Vertical motion: If t be the time taken by the packet to reach the victim, we have for vertical motion,
`H= 1/2 gt^2 or, t= sqrt((2H)/g)` ........i.
Horizontal motion: If D be the horizontal distance travelled by the packet, we have D= ut. Putting t from i,
`D=sqrt((2H)/g)`
The distance between the victim and the packet at the time to release is
`sqrt(D^2+H^2)=sqrt((2u^2H)/g+H^2)`
