198. The e.g. of a thin hollow cone of height h, above its base is diminished by

199. From a solid cylinder of height 8 cm and radius 4 cm, a right circular cone is scooped out on the same base and having the same height as that of the cylinder. The c.g. of the remainder is at a height of

200. The acceleration of a train starting from rest at any 1 instant is 6(V + 1) m/sec2 where V is the velocity of the train in m/sec. The train will attain a velocity of 36 km/hour after travelling a distance of

201. The motion of a particle is described by the relation x = t2 ? 10t + 30, where x is in metres and t in seconds. The total distance travelled by the particle from t = 0 to t = 10 seconds would be

202. Three forces which act on a rigid body to keep it in equilibrium. The forces must be coplanar and

203. The equation of motion of a particle starting from rest along a straight line is x = t3 ? 312 + 5. The ratio of the velocities after 5 sec and 3 sec will be
