# Q.6. Two + 1 C and + 4C are placed X-axis. If other charge q is placed in between the two charges, such that this system is in equilibrium. The magnitude of q is (1) $\frac{3}{4}$ C (2) $\frac{9}{16}$C (3) $\frac{4}{9}$ C (4) $\frac{9}{4}$ C

Now calculate the value of q again

The charge q at distance x
First we have to find x
