Answer:
(a) Measured change in mass (Δm) = BVL/Rg
(b) Total measured mass M' = M - BVL/Rg
Explanation:
Current (I) across is coil is given by the formula;
I = V/R ------------------------1
The magnetic force is given by the formula;
Fb = B*I*L -------------------2
Putting equation 1 into equation 2, we have;
Fb = B*V*L/R -------------------3
Change in mass (Δm) is given as:
Δm = Fb/g -----------------------4
Putting equation 3 into equation 4, we have;
Δm = BVL/Rg
Therefore, change in mass (Δm) = BVL/Rg
2. Since B runs from North to South and current running from East to West, then the magnetic force is directed upward.
Therefore,
Total measure mass M' = M - BVL/Rg
