Question

A force of 600 kg weight can be breaker wire the force necessary to break another wire of the half cross sectional area will be

1. 1200kg-wt

2. 300 kg-wt

3. 150 kg-wt

4. 900 kg-wt​

Answer 1

Answer:

since the cross secton is half therefor

we say the surface area decreases then then the pressure increases
