Mass of trolley (m1)=3.3kg
Mass of connected weight (m2)=2.2kg
Now, Let the common acceleration be a and the clamping force be T (tension in the string).
Now,
T=m1a....(i)
m2g−T=m2a...(ii)
From equation (i) and (ii)
a=m1+m2m2g
Now, substituting the values,
⇒a=3.3+2.22.2×10m/s2
⇒a=5.522m/s2
⇒a=4m/s2
hence, the required tension in the string or the clamping force
T=m1a=3.3×4N
⇒T=13.2N
