The plates of a parallel plate capacitor are separated by d. Two slabs of different dielectric constant K_1 and K_2 with thickness \frac{3}{8} d and \frac{d}{2}, respectively are inserted in the capacitor. Due to this, the capacitance becomes two times larger than when there is nothing between the plates. If K_1=1.25 K_2, the value of K_1 is: [NEET 2025]
