27A particle moves on a circular path with constantspeed 15' m/s. Find the change in speed &magnitude of change in velocity, when particlecompletes half revolution :-(1) 30 m/s, 30 m/s 2) 0, 30 m/s(3) 0, 15 m/s20.(4) 0, 0 |

Answer» Change in speed will be 0' because its given constant also, there is change in Velocity, due to change in direction, after half revolution so, ∆v = 15-(-15) = 30 m/s option 2 |
