Two boys are applying oppositely
directed, and equal in magnitude,
forces on a box as shown in the
figure.
In such a case, the force of friction, that would exist between the lower end of
the box and the ground, would be called-
sliding friction
static friction
fluid friction
rolling friction
3.
Four students were asked to arrange the (frictional) forces, due to rolling, static
and sliding friction, in an increasing order. Their arrangements are listed below.
The correct arrangement is
rolling, static, sliding
static, sliding, rolling
rolling, sliding, static
static, rolling, sliding
