Abhi tak maine jitni book padhi hai 1 to 9 tak usme ncert hi aisi ek book hai jo doubt clear karne ki jagah doubt badhati hai

But sir why is the sum of the three forces zero?

Sir agar isme direction bhi btani hui to i mean direction kaise find out karenge along F1,F2 and F3 ?

[@anandu5820]

What did you do at the end How did they become equal?

[@droidly_]

I used ( F^2 + F^2 - 2F^2 Cos 60 )^1/2 instead of ( F^2 + F^2 + 2F^2 Cos 120 )^1/2 because Cos(180 - Q) = - CosQ

Then, how can we say that sum of the three forces will be zero (as it is given in book)

Yes, the resultant of forces be zero, I will explain it in exercise problems.

why do we take it as COS 120 why not sin

It’s derived formula, you can check it in your book

in book F1 + F2+ F3 IS EQUAL TO 0 HOW???

Watch it again after half an hour

[@snehachauhan237]

But how the magnitude of two forces can be equal

[@PhysicswithGaurav]

Charges have same value ( magnitude) and the distance between all the charges same, thats why.
