Question

A wooden block is slide over a surface. A student puts weight on the block, What happens to the reading of spring balance?​

Answer 1

Dear Himanshu,

◆ Answer -

Reading of the spring balance will increase on adding weight to the block.

● Explaination -

• Spring balance is used to measure force required to move(slide) the block.
• Force required to slide the block is directly proportional to mass of the block. i.e. F ∝ m.
• Hence, when weight is added to block, force required to move block increases resulting in increased reading of spring balance.

Thanks for asking..

Answer 2

Answer:

Increase in the reading

Explanation:

As the spring balance will measure the normal reaction of the block.

therefore on adding extra weight to the block its normal reaction will automatically increase which will increase the reading of spring balance

Hope this helps.
