Question

All the edges of a block with parallel faces are unequal. Its largest edge is twice its shortest edge. The ratio of the maximum to the minimum resistance between parallel faces is, 8, 4, 2, 1

MARKS App · Accepted Answer

Let the length of various edges in increase order be l , x , 2 l respectively R m a x = ρ 2 l x l = 2 ρ x ; R m i n = ρ l 2 l x = ρ 2 x ∴ R m a x R m i n = 4
