Answer:
Centripetal acceleration of boy on a string is 47.02 m/s²
Explanation:
It is given that,
Radius of the circle, r = 1.8 m
Speed of the ball, v = 9.2 m/s
Centripetal acceleration is given by :
Hence, the centripetal acceleration of a ball on a string that is whirled horizontally over a boy’s head is 47.02 m/s²

Answer:
it must be helical motion in which the charge particle will move uniformly along z axis and simultaneously it will move in circular path in xy plane.
Explanation:
Magnetic field is along z axis while velocity is in x-z plane
so we will have
so here we can say
so we will have
so here the net force on the charge is perpendicular to its x directional velocity along - Y direction
So due to this component of motion it will move along a circle while other component of the motion will remain uniform always
So here it is combination of two parts
1) Uniform circular motion
2) Uniform motion
So we can say that it must be helical motion in which the charge particle will move uniformly along z axis and simultaneously it will move in circular path in xy plane.
