Solution

Step1: Given data
Pressure at the surface of the earth(P) = $10^{5} N m^{- 2}$ ,
Surface area (A) = $3 m^{2}$
Thrust (force) = ?
Step 2: Formula used
$P r e s s e u r e = \frac{T h r u s t}{A r e a} . . . . . . . . . . . (a)$
Step 3: Calculating the thrust( force)
Putting all the given values in equation (a)
$T h r u s t = P r e s s u r e \times A r e a T h r u s t = 10^{5} N m^{- 2} \times 3 m^{2} T h r u s t = 3 \times 10^{5} N .$
Hence, the thrust (force) exerted by the object is $3 \times 10^{5} N .$
