Answer:
Maximum charge will be 
Explanation:
We have given force ion the moving charge 
Maximum speed of the moving charge v = 30 m /sec
Magnetic field 
We have to fond the charge
Force on moving charge is given by

So 

Maximum charge will be 
When a substance is heated the average kinetic energy of molecules increases and they start moving with an increased speed.As a result between mean separation between the molecules also increases
