A letter 'A' is constructed of a uniform wire with resistance $\displaystyle 1.0 \Omega$ per cm . The sides of the letter are $\displaystyle 20$ cm and the cross piece in the middle is $\displaystyle 10$ cm long. The apex angle is $\displaystyle 60$°. The resistance between the ends of the legs is close to :
Official answer
(4)
$\displaystyle 26.7 \Omega$
