Answer:
the answer is 12 because if your magnetic value and Electric field is 3.2 the answer will be 12
The correct answers would be B, and d
Answer:
1.2cm
Explanation:
V=(2ev/m)^1/2
=(2*1.6*10^19 x2500/ 1.67*10^27)^1/2
=6.2x10^5m/s
Radius of resulting path= MV/qB
= 1.67*10^-27x6.92*10^6/1.6*10^-16 x0.6
=0.012m
=1.2cm
It causes or makes a magnetic field.
