For the equation FpropA^(a)v^(b)d^(c), where F is the force, A is the area,v is the velocity and d is the density, the values of a,b and c are respectively :

Answer»

`1,2,1`
`2,1,1`
`1,1,2`
`0,1,1`

SOLUTION :Taking the dimensions of both sides
`[MLT^(-2)]=[L^(2a)][L^(b)T^(-b)][M^(c)L^(-3c)]`
`=M^(c)L^(2a+c-3c)T^(-b)`
`:.c=1|{:(2a+b-3c=1),(2a=-2+3+1),(a=1):}|{:(-b=-2),(b=2):}`
Hence `FxxA^(1)V^(2)d^(1)`
