^{Guys attempt this mock test... I will be providing the ranks of the participants, their scores....and the answer key at 10:00 pm tommorow....so hurry up... only write the serial number of the question and the answer in front of it out of A,B,C,D,E}

^{For assertion reason consider this
a) both correct but correct explanation
b) both correct but wrond exp
c) A is true but R is wrong
d) A is wrong but R is true
e) both wrong}

^{Q. 1 Assertion:A cyclist bends inwards while negotiating a curve}

^{Reason :By bending he lowers his center of gravity}

^{Q. 2 Assertion:Banking of road reduces the wear and tear of tyres while turning}

^{Reason :component of normal reaction provides the centripetal force which is otherwise provided by friction}

^{Q .3 Only One correct}

^{A body is placed on a rough incline, when the angle of inclination is increased from 0 to 90 the contact force between the block and the plane}

^{a) remains constant}

^{b) first remains constant and then decreases}

^{c) first decreases then increases}

^{d) first inc the dec}

^{Q4 Fill in the blank.}

^{In order to raise a mass of 100 kg a man of mass 60 kg fastens a rope to it and passes it over a smooth pulley.He climbs the rope with an acc. 5g/4 relative to the rope.The tension in the rope is.............}

^{Q 5 Match the column}

^{If net force on a system of particles is zero then}

^{Table 1 Table 2}

^{a) acc. of COM p) constant}

^{b)momentum of COM q)zero}

^{c)velocity of COM r) may be zero}

^{d)velocity of individual particles s) may be constant}

^{Q 6.More then one correct}

^{If all matter were made up of electrically neutral particles such as neutrons}

^{a) there would be no friction}

^{b) there would be no tension in the string}

^{c) it would not be possible to sit on a chair}

^{d) the earth could not move around the sun.}
