Force= mass × acceleration
= 10 ×9.8 = 98 N

Area = 20 × 10 = 200 cm² = .2 m²

pressure= force / Area

pressure= 98/.2 = 490 N/m²

K29902: But answer is B where 1 more zero
Physicist182: Correct answer is 49 N/m²
Physicist182: No it's incorrect
Physicist182: Area = 20cm × 10 cm= .2m ×.1 m = .02 m²
Physicist182: Pressure=98 /.02 = 4900 N/m²
Physicist182: Now it's correct
Physicist182: I did wrong calculations in hurry Sorry for it
