Answer:
27 . 10^-7 or 27/1000
Explanation:
We use the Coulomb Law
k = Coloumb Constant
q1 and q2 are the charges
d is the distance between the spheres
Answer:
Magnetic field, B = 0.004 mT
Explanation:
It is given that,
Charge, 
Mass of charge particle, 
Speed, 
Acceleration, 
We need to find the minimum magnetic field that would produce such an acceleration. So,

For minimum magnetic field,



B = 0.004 T
or
B = 4 mT
So, the magnetic field produce such an acceleration at 4 mT. Hence, this is the required solution.
Answer:
