In railway stations __________ balances are used.

While  measuring the length of a piece of a chalk by Vernier calipers. The main scale reading is found  to be  between 5.2cm and the 5th division of a vernier scale is found to coincide with a division on the  main scale.  Find the length of the chalk if the least count  of the vernier is 0.01cm and zero error is  0.02cm.

A Vernier Callipers with 1MSD = 1cm has 5 divisions as the vernier. The least count is

The angular amplitude of the simple pendulum should not be more than which of the following?

A physical  balance is used in the laboratories, to find out the mass of a substance correct to a  

To find the weight of a person ______________ balance is used.

If an instrument gives nearly equal values in repeated measurements, it possesses

If the  zeroth division of the vernier is on the left of the zeroth division of the main scale,  then the  zero error and zero correction are as follows.

The number of oscillations that the  bob makes per second is called its
