Your sliding contact resistor is controlled by a 10-turn dial with each increment of the dial marked for 0.01 turns. what is the unknown resistance in the balanced wheatstone bridge when the dial is turned to 6.46 (n1) and the standard resistance is 2ω.

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

find the sum of the two horizontal vectors and the sum of the two vertical vectors
