Case (IV)
With the suspension point 30cm from the left edge of the meter stick, hang a 200g mass 10cm from the left edge of the stick. Calculate the mass you must hang at a point 40cm to the right of the pivot point such that the stick hangs level and write it on the sketch.

A pin is 20 cm away from the left edge of the meter stick.
An unknown mass, m1, is placed a distance 5cm from the leftedge.
m2 = 12 kg placed 40 cm from the left edge.
The meter stick that the masses hang on, m(stick) = 1kg
A center of gravity is located 50cm from the left edge.

Two weights are hung on eiher side of the pivot support of a meterstick. Ignore the weight of the meter stick and assume it is pivoted inthe middle. What is the size of the mass that must be hung on the leftside of the stick to balance it.? 3oo grams is hung 30 cm away from thepivot point on the right. On left what is the weight that has to behung 38cm away from pivot point to balance it.?

A meter stick lies on the bottom of a 100-cm-long tank with its zero mark against the left edge. You look into the tank at a 30 degree angle, with your line of sight just grazing the upper left edge of the tank. What mark do you see on the meter stick the tank is (a) empty, (b) half full of water, and (c) completely full of water?
