Find constant of variation and write equation of variation for the example given below.
s ∝ \[\frac{1}{t^2}\] ; if s = 4 then t = 5
उत्तर
`"s" = "k"/"t"^2` ...(k is a constant)
s × t2 = k ...(equestion of variation)
Substituting s = 4, t = 5
s × t2 = k ...(equation )
4 × 52 = k
4 × 25 = k
k = 100 ...(The constant of variation)
s × t2 = 100 ...(is the equation of variation)
