Physics Railway tracks are banked on curves to avoid frictional force between the tracks and wheels the train may not fly off in the opposite direction necessary centrifugal force may be obtained from the horizontal component weight of the train necessary centripetal force may be obtained from the horizontal component of the weight of the train to avoid frictional force between the tracks and wheels the train may not fly off in the opposite direction necessary centrifugal force may be obtained from the horizontal component weight of the train necessary centripetal force may be obtained from the horizontal component of the weight of the train ANSWER DOWNLOAD EXAMIANS APP
Physics A boy is swinging a ball attached to a string in a horizontal circle. If the string snaps It will continue to travel along a tangent to the circle at the point the ball was at the time of snapping and finally fall down None of these The ball will travel towards the center of the circle and fall down It will fall down at the same place where the string breaks It will continue to travel along a tangent to the circle at the point the ball was at the time of snapping and finally fall down None of these The ball will travel towards the center of the circle and fall down It will fall down at the same place where the string breaks ANSWER DOWNLOAD EXAMIANS APP
