Answer:
Mass of ion will be
Explanation:
We have given ion is triply charged that is
Radius r = 36 cm = 0.36 m
Velocity of the electron
Magnetic field B = 0.55 T
We know that radius of the path is given by

Answer:
7.04 m
Explanation:
t = Time taken
u = Initial velocity
v = Final velocity = 0
s = Displacement on Earth = 1.2 m
a = Acceleration due to gravity on Moon = 1.67 m/s²
a = Acceleration due to gravity Earth= 9.81 m/s²
Accelration going up is considered as negetive
Initial Velocity of the ball
Assuming that the ball is thrown with the same velocity on the Moon, displacement of the ball is
The displacement of the ball on the moon is 7.04 m
