Question

draw free body diagram and find acceleration and force bye making equations please i request to tell the proper answer except of anything wrong ​

Answer 1

Answer:

A = F / m1+m2+m3  and F1,2 = m1+m2/m1+m2+m3

Explanation:

this equations are due to contact force .

Use these formulae. u will get answer easily. F1,2 =  $\frac{m1+m2}{m1+m2+m3}$
