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.
