Question

Pleased explain this in detail,Answer is option 2​

Answer 1

Answer:

Hey mate !!

Here is your answer

Explanation:

Given that,

Mass of A mA=10kg

Mass of B mB=5kg

Coefficient of friction μ=0.2

Now, the tension is

  T=mbg

 T=5×10

 T=50N

Now, we consider the combination of A and C

Then,

  T=μR

 T=0.2(mA+mC)g

 50=0.2×10×10+0.2mC×10

 50−20=2mc

 mc=15kg

Hence, the minimum mass of C is 15 kg
