    Q8. To determine the coefficient of friction between a rough surface and a block, the surface is kept inclined at 45° and the block is released from rest. The block takes a time t in moving a distance d. The rough surface is then replaced by a smooth surface and the same experiment is repeated. The block now takes a time t/2 in moving down the same distance d. The coefficient of friction is

    (A) 3/4

    (B) 5/4

    (C) 1/2

    (D) 1/√2

    Ans: (A)

    Q9. A wooden block is floating on water kept in a beaker. 40% of the block is above the water surface. Now the beaker is kept inside a lift that starts going upward with acceleration equal to g/2. The block will then

    (A) sink

    (B) float with 10% above the water surface

    (C) float with 40% above the water surface

    (D) float with 70% above the water surface

    Ans: (C)


    The block will float with 40% above the water surface.

    Q10. An electron in a circular orbit of radius .05 nm performs 1016 revolutions per second. The magnetic moment due to this rotation of electron is (in Am2)

    (A) 2.16 × 10–23

    (B) 3.21 × 10–22

    (C) 3.21 × 10–24

    (D) 1.26 × 10–23

    Ans: (D)


    Let the magnetic moment be M.
