If three forces vec(F_(1)),+vec(F_(2))andvec(F_(3)) are represented by three sides of a triangle and vec(F_(1))+vec(F_(2))=-vec(F_(3)) , then these three forces are concurrent forces and satisfy the condition for equilibrium . Statement II : A triangle made up of three forces vecF_(1),vecF_(2)andvecF_(3) as sides taken in the same order ,satisfy the condition for translatory equilibrium . In the light of the above statements ,choose the most appropriate answer from the options given below :

The matallic bob of a simple pendulum of mass 0.5 kg carries a positive charge of 0.25 C .If the pendu-lum is suspended in an electric fielf of strength 15 N C^(-1) directed from east to west, state the forces acting on the bob and derive the condition for equilibrium. Also find the angle subtended at the equilibrium. (Take g = 10 ms^(-2) )

If the rate constant of forward reaction is triple of rate constant of backward reaction under identical condition at equilibrium, then K_(eq) for the reaction is
