Hi,
       When there are 2 forces of equal magnitude acting with an angle of 60 degree to each other the Resultant force is 10√3 N
       ( this is calculated using R^2 = P^2 + Q^2 + 2PQcos(x) )

                  using 
                          F = ma
                     10√3 = 10 * a
                           a = √3 m/s^2
