xi -2j + 5k , i + yj -zk എന്നീ സതീശങ്ങൾ സമരേഖീയമാണ് എങ്കിൽ xy²/z =

A4/5

B3/5

C-3/5

D-4/5

Answer:

D. -4/5

Read Explanation:

xi -2j + 5k , i + yj -zk എന്നീ സതീശങ്ങൾ സമരേഖീയമാണ്

x1=2y=5z=λ\frac{x}{1} = \frac{-2}{y} =\frac{ 5}{-z} = λ

x=λ,y=2λ,z=5λ x=λ , y=\frac{-2}{λ} , z=\frac{-5}{λ}

xy2z=λ(2λ)25λ=λ2×45×λ2=45\frac{xy^2}{z}=\frac{λ(\frac{-2}{λ})^2}{\frac{-5}{λ}}=\frac{λ^2\times 4}{-5\timesλ^2}=\frac{-4}{5}
