Question : 59
Total: 75
A mass
M
is placed on a very smooth wedge resting on a surface without friction. Once the mass is released, the acceleration to be given to the wedge so that
M
remains at rest is
a
where
( 1998 )
a
is applied to the left and
a
=
g
tan
θ
a
is applied to the right and
a

Solution:
The pseudo acceleration for the body
a
′
=
a
If the pseudo force
M
a
cos
θ
=
M
g
sin
θ
,
then the body will be at rest,
a
=
g
tan
θ
This horizontal acceleration should be applied to the wedge to the left.
