Four forces act on a particle as shown in the figure such that net force is zero. Then consider following statement `:-` `(A)` Magnitude of `vec(f_(1))` is `10N` `(B)` Magnitude of `vec(f_(1))` is `20N` `(C)` Magnitude of `vec(f_(2))` is `10N` `(D)` Magnitude of `vec(f_(2))` is `20N`A. Only `A`B. Only `C`C. Only `D`D. Only `A` & `D` |
