In the arrangement shown in the figure there is friction only
between the light string and the sharp spike at the point P. When the
blocks are in motion, the tensions in the vertical and horizontal
sections of the string are 4 N & 3 N respectively. The co-efficient of
friction between the string and the spike is equal to

A0.1B0.2C0.5D1

[IMAGE] N = 5
on string
$4 - 3 - \mu N = 0$
$\mu N = 1$
$\mu = 0.2$
