Question

two objects a and b are attached to a pulley, weight of a is 10kg and b is 2kg. find the tension of the string.

Answer 1

Answer:

110N

Explanation:

to answer this first we find acceleration ,

(assuming as 10)  a=$\frac{10*10-2*10}{12}$

a=20/3

so for tension

20/3=$\frac{T-10*10}{10}$

10=T-100

thus tension=110N
