Uniform cube of mass m and side a is placed in a frictionless horizontal surface. A vertical force F is applied to the edge as shown in the figure.
Match the following
a) |
i) cube will move up |
b) |
ii) cube will not exhibit motion |
c) |
iii) cube will begin to rotate and slip at A |
d) |
iv)normal reaction effectively at |
(a) – (ii), (b) – (iii), (c) – (i), (d) – (iv)
Let be the moment of force due to F at A and
be the moment of force due to mg at A
is anti-clockwise whereas is
clockwise
and
Cube will rotate only if
If normal reaction force acts effectively at from A
implies
So due to block will not moing
