Question

The minimum force required to start pushing a body up a
rough (frictional coefficient p) inclined plane is F, while the
minimum force needed to prevent it from sliding down is
F. If the inclined plane makes an angle e from the horizontal
such that tane = 2u then the ratio
is
(1) 4
(3) 2
(2)1
(4) 3​

Answer 1

Answer:3

Explanation:

if tane=2p answer is

    mgsine+pmgcose/mgsine-pcose

   than answer is 3
