  • Question 10
    1 / -0
    If $$F = n$$ and $$E = n + 1,$$ then using Euler's formula, the value of $$V,$$ is:
    Solution
    Given:-
    $$F=n$$
    $$E =n+1$$ 

    As per the Euler's formula,
    $$F-E+V=2$$
    $$\Rightarrow n-(n+1)+V=2$$
    $$\Rightarrow n-n-1+V=2$$
    $$\Rightarrow V=3 $$

    Hence, option $$A$$ is correct.
