Question

A pressure of 50Pa is applied when an acrobat balances on a plank. What pressure will the same acrobat apply if the plank is cut in half?

Answer 1

Explanation:

given , p = 50 Pascal

as , p = F / A

now , plank is cut half that means

it's area becomes half than

previous one . and force is same .

hence

p` = F / ( A/2)

2F / A

hence new pressure = 2 × 50

100 pascal
