Expert Solution
Step 1

Given data is as per question:

m1=8.2×10-2 kgr1=0.247 mrCG=0.254 m

 

Step 2

According to data in activity one;

rCG avg=rCG1+rCG2+rCG33=0.504+0.503+0.5043rCG avg=0.504 mms=ms1+ms2+ms33=0.0789+0.0791+0.07923ms=0.0790 kg

Fpin=msg+m1g=0.0790×9.8+8.2×10-2×9.8=9.8×0.0790+0.082=1.578 N
