1.	We open a file keeping one flap on a table. Each flap is square, of mass m and dimension (30 xx 30) cm^(2). Assume that the file does not slip on thetable -
Answer» The maximum height attained by the centre of mass of the COMPLETE file is `7.5 cm` The maximum height attained by the centre of mass the complete file is `15 cm` The minimum FORCE required to hold the flap at REST at `60^@` to horizontal is `(mg)/(4)`. The minimum force required to hold the flap at rest at `60^@` to the horizontal is `(mg)/(2)`. Answer :A::C
