Let mP,mQ, and mR be the masses of the bodies P,Q, and R.
Step 1: Write the formula for mass using force and acceleration.
We know that F=m×a. Rearranging, m=‌

F

a

.
Step 2: Find the mass of each body.
For P,mP=‌

F

18

For Q,mQ=‌

F

9

For R,mR=‌

Step 3: Add all the masses to get total mass.
mPQR=mP+mQ+mR
So, mPQR=‌

Step 4: Find the acceleration of the combined mass with the same force.
Acceleration, aPQR=‌
