It is a scaler because it’s only fully describes by a magnitude and a numerical alone
Because its a vacuum, there's no air resistance, they will fall at same time
Applying gravity acceleration rule g=9.8m/s which is taken as 10m/s sometimes.
Answer:
F = I L X B = I L B sin theta
F = 5.2 * 1.2 * .87 sin 45 = 3.84 N in the direction of (L X B)
Note: L and B must be at right angles for F = I L B
