Answer Key : (a) -

(a)

The force required to topple the block about

and

Force between  N will do neither sliding or slipping

Force between  N will cause slipping

Force above 55 N will topple the block

Next Question :

Following question is based on letter analogy.  There are two pairs of letter combinations in each question.  The first (left-side) pair has some relationship between its members.  In the second pair, one member is missing.  Find this out from the options.  Such that this pair has similar relationship as the first pair.
