A point moves with retardation along a circle of radius R so that at any moment Ram and Shyam are walking on two perpendicular tracks with speeds 3m s and 4m s respectively At a certain moment say t 0s Ram and Shyam at 40m and 20m away from the intersection tracks respectively and moving towards the intersection of the tracks A Shortest distance between them subsequently is 15m B Shortest distance between them subsequently is 20m C The time when they are at shortest distance from each other is 8s D The time when they are at shortest distance from each other is 9s
