- Akash Anand Wrong answer...but keep trying
- Himanshu Giria Sir is the friction between both the surfaces is. 0 .42
- Akash Anand Yeah friction is there on all the surfaces.
- Himanshu Giria Sir plz tell the ans
- Akash Anand Not yet..just keep trying.
- Himanshu Giria Sir I tried
the ans is coming 13.2 again and again
4811st equation-f1=0.42*2*10=8.4N
2nd equation-F=f1+f2+6a[where f1 is d friction bet. the 2kg and 6kg block and f2 is d friction bet. 6kg and the surface and a is the acc. with which the 6kg block is to be pulled out]
f2=0.42*10*8=33.6N
F=8.4+33.6+6*1.5=51N
- Akash Anand Excellent Job
