    Hello once more again sir 🥰 . Sin in our very first example , how did u know that the force betwen sphere b and A is attraction bc on sphere b we are only give mass of that sphere not the charge .

      @@MlungisiNkosi I take back my statement. Your answer is correct sir. I just didn't know how to use the values when you use the angle in that top right corner. So I used some "mathematical gymnastics" by using the sum of angles of a triangle formula to ge the angle in the bottom left and then using tan from that angle and then I got the same answer

    • @MlungisiNkosi

      The only reason ball B was in that position is because A was pulling on it. That’s why I said attraction… I hope that makes sense.
