14, Banking of roada serves the purpose of A reducing frictioa berween vehicle wheels und the ground Il increastng friction hetween vehicle wheels and the ground C increasing speed of vehicles D. reducing skidding wearing away of the wheels of vehickes E making a road look awesome 15. A body in circular mution es periences a force which is A directed towards u fixed point B proportional to the velocity C proportional to the radius of the circular path D proportional to the squre of the radiun of the puth E proportional to its density 16. A body moving round a circular path of radius, r with conatant angular speed cp has a lineur constunt speed of magnitude v. The correct mlutionship hetween r, ind v is D. ap = tv Er= 17. The motion of a body is simple harsonic if the A acceleration is always directed towants a fiked point H purth of motion is a straight line C acceleration directed towards a fixed point and proportional to its distunce from the point. D acceleration is proportional to the square of the distance from a fixed point. E mass is proportiomal te the acceleration 18. A simple pendulum makes 50 oncillations in one minute. What in its perind of oscillation? A 0.02 R0,20 CO 83 D. 1.20 E 2.6s 19. The umplitude of the motion of a body perfoming SHM decreases with time because A frictional forces idissipate the energy of motion H the frequency of oscillation varies with time C the period of oscillation varies with time n energy is supplied hy some external agents E the mass of the string reduces with time 31. Which of the following would reduce the fraquensy of oscillation of a simple pendulum? A increasing the mass of the bob i decreasing the mus of the bob C increusing the length of the string D decrensing the length of the string E using a white hob 21, A swinging pendulum between the rest position and its maximum displacement pousesses A kinetie energy only i putcutial cuesgy uuly C gravitational energy only D. hoth kinetic and potential energy. E inertia kinetic and potential energy 22. A stationury object of mass 4kg is set in mtion by a net fonce f 5ON, If the object attains a speed of Sms" in time t, calculate the value of t A 0.20 R 0.40 C. 0.63 D. 0.80s E 0.Sts 14, Banking of roada serves the purpose of A reducing frictioa berween vehicle wheels und the ground Il increastng friction hetween vehicle wheels and the ground C increasing speed of vehicles D. reducing skidding wearing away of the wheels of vehickes E making a road look awesome 15.
