Question

plz answer fast as must as possible

Answer 1

Hey there!!

.

We know that P=F/Area of contact

.

F = mg= 5 kg × 9.8 m/s²= 49 N

In case (a)

.

Area of a side = length × breadth

= 20 cm × 10 cm

= 200 cm²

= 0.02 m²

P= 49 /0.02= 2450 N/m²

.

In case (b)

Area= length × breadth= 40 × 20= 800= 0.08 m²

Pressure = 49/0.08= 612.5

.

Hope it helps :))
