The length of a pencil is measured to be 10.00 cm with a ruler. What is the fractional error in the length of the pencil?
0.05%
0.005
0.005 cm
0.005 mm
None of the above.
Least count with which measurement has been done = 0.01 cm
That means ∆L = 0.01 cm
So fractional error = ∆L/L = 0.01/10.00 = 0.0001
So none of the above

A student uses a ruler graduated in centimeters to measure the length of a pencil. The pencil's length is about halfway between the 10-cm and 11-cm marks. The student should approximate the measurement as ____ cm
71. A student makes a homemade resistor from a graphite pencil 5.00 cm long, where the graphite is 0.05 mm in diameter. The resistivity of the graphite is 5 ρ 1.38 10 / m − = ×Ω . The homemade resistor is place in series with a switch, a 10.00-mF capacitor and a 0.50-V power source. (a) What is the RC time constant of the circuit? (b) What is the potential drop across the pencil 1.00 s after the switch...
A uniform ruler of 1-m length is supported using a knife-edge clamp at 20-cm mark. The ruler is balanced by hanging a 320-g weight at 5-cm mark along the ruler. What is the mass of the ruler? What the torque on the ruler due to the normal force from the clamp?
You have a defective ruler which has an error of 2 mm in every 10 cm. If you do measurements with this ruler, your data will have: O Random error O No error Systematic error
A pencil (mass 12.0 g and length 18 cm) is initially balanced so that it is standing vertically on a flat table. If the pencil then falls, what is its angular velocity just before it strikes the tabletop? Assume the mass of the pencil is distributed uniformly and the end of the pencil in contact with the table does not slip.

A balance and torque experiment is conducted with a balanced ruler (that is, the pivot point is in the middle). Length of the ruler. 1 m Weight of the ruler 8 N te of 1.00 Mass 1: 148 g. This mass is placed at the 44-cm mark on the ruler. What should be the magnitude of the second mass? Answer estion The second mass is to be placed at the 85-cm mark on the ruler. Check

A 60 cm ruler which has a 10g weight is on the pivot
point at 19cm on a ruler. The center of gravity for the ruler is at
the 29cm point. You have a 20g weight to balance the ruler. At what
point on the ruler will you hang the weight to make the system
equilibrium?
