Physics A boy is swinging a ball attached to a string in a horizontal circle. If the string snaps The ball will travel towards the center of the circle and fall down 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 It will fall down at the same place where the string breaks The ball will travel towards the center of the circle and fall down 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 It will fall down at the same place where the string breaks ANSWER DOWNLOAD EXAMIANS APP
