Planetary Nebula are the outer layers of a star that are lost when the star changes from a red giant to a white dwarf. A star is a luminous globe of gas producing its own heat and light by nuclear reactions (nuclear fusion). They are born from nebulae and consist mostly of hydrogen and helium gas.

Answer:
0.855 N
Explanation:
Using
F = BILsinФ.................... Equation 1
Where F = magnitude of the force exerted on the wire, B = magnetic Field, I = current, L = Length of the wire in the magnetic Field, Ф = angle between the wire and the magnetic field.
Given: B = 0.95 T, I = 15.0 A, L = 2r, r = radius = 3.0 cm = 0.03 m L = 2×0.03 = 0.06 m, Ф = 90° (perpendicular)
Substitute into equation 1
F = 0.95(15)(0.06)sin90°
F = 0.855 N.
Hence the magnitude of force that is exerted on the wire = 0.855 N
It would be a) 2 electrons
