Answer 1

How to measure the gravitational mass of a solid using a spring balance?
In real lab:

 

Take a metallic solid block.Tie it with a thin strong thread to hang it on the hook of the spring balance.Note the least count of the spring balance.Hang the block on the hook of spring balance. It is better to hang the spring balance with the help of an iron stand or clamp stand so that it remains static while noting the mass of the block.Carefully observe the gravitational mass of the solid block and note it down. Repeat it thrice and calculate mean of the three readings taken.
To perform the simulator:Note the least count of the spring balance.Click on any one of the given solids such as stone, steel ball, wooden block, copper lock, and copper block to measure its gravitational mass.Once you click on it, the selected solid will shown as hung on the spring balance.Mouse over the scale on the spring balance where the red indicator points to get the readings.You can also check your readings on the space given.

 

Now we need to find the Mass of the solid.Mass of the solid, Now we need to find the volume of the solid as you know,Density, 

a) As performed in a real lab:

 

Take a graduated glass cylinder of proper size and capacity. Fill it with water up to a known volume level mark.Tie the rectangular metallic block by a thin strong thread and immerse it fully in water taken in the graduated cylinder. The block displaces water and the water level rises. Note the position of water level (meniscus) keeping the eye in horizontal position with the level (to avoid error due to parallax).Find the difference of two positions of the water level to find volume of metallic block immersed.Repeat it thrice and calculate the mean of three observations taken.

b) As performed using the simulator:Click on the button, “Volume” to measure the volume of the solid.Click on one of the given solids to measure its volume.Now mouse over the cylinder to measure the water rise in the cylinder.You can also check your readings on the space given and by clicking on the button, “Check”.Calculate the density using the formulae and check your results in the respective space.
