Question

The spring balance used for pulling the block has least count of 0.5 kgwt. the block starts moving when pointer is at 25th division. find the applied force?

Answer 1

1 kgwt is the weight of a mass of 1kg and is equal to 9.81 N according to w=mg, where w is weight, m is mass and g is acceleration due to gravity. The spring balance has graduations in0.5kgwt which is equal to (9.81*0.5) = 4.91N The block starts moving when the pointer is at the 25th division, which is ...
