The two equal positive charge Ware fixed at points (-a,0)and(a,0) on the X-axis. An opposite charge -q at rest is released from point (0,a)on the y-axis.The q charge will be.. {answer is =Execute the oscillatory periodic motion but not SHM}

In the reaction A + 2B ⇌ 2C, if 2 moles of A, 3 moles of B and 2 moles of C are placed in a 2 L flask and
the equilibrium concentration of C is 0.5 mol/L. The equilibrium constant (KC) for the reaction is.....and please tell how you know that the reaction is going forward .. imean how to calculate the reaction quotient ???
