What is the relationship between a magnets magnetic force and a magnetic field?

i think this could help you

3.57N

Explanation:

given

Speed of rotation, N = 1300 rpm

diameter, d = 35 cm, so that

radius, r = 17.5 cm = 0.175 m

mass of drop = 1.1 g = 1.1*10^-3 kg

Angular speed of water, ω = 2πN/60

ω = 2π*1300/60

ω = 8169.2/60

ω = 136.15 rad/s

apparent weight will be gotten by

W(a) = mω²r

W(a) = 1.1*10^-3 * 136.15² * 0.175

W(a) = 1.1*10^-3 * 18536.82 * 0.175

W(a) = 3.57 N

Therefore, the apparent weight of 1.1 g of water is 3.57 N
