Cumulus clouds are cotton like and fluffy but when clumped together may produce thunderstorms.
Swinging needs to be the first skill mastered
Answer:
The mass is 
Explanation:
From the question we are told that
The speed of the charge is 
The magnetic field is 
The radius is 
The value of the charge is 
The centripetal acting on the charge moving in the circular orbit is mathematically represented as

Now this centripetal force is due to the force exerted on the charge by the magnetic field on the charge which is mathematically represented as

At the maximum of this magnetic force 
So


Now given that it is this magnetic force that is causing the circular motion we have that

=> 
=> 
substituting values
