a) 0
b) 2
c) 4
d) 6
(ii) Through how many of the cube's faces is the electric flux zero?
a) 0
b) 2
c) 4
d) 6

explanation: magnetic pole, region at each end of a magnet where the external magnetic field is strongest. the south-seeking pole, or any pole similar to it, is called a south magnetic pole. unlike poles of different magnets attract each other; like poles repel each other.

c.the charges if the proton and electron and gravity
