Question

why are some of the Peninsula rivers east flow

Answer 1

The main water divide in peninsular rivers is formed by the Western Ghats, which run from north to south close to the western coast. Most of the major rivers of the peninsula such as the Mahanadi, the Godavari, the Krishna and the Kaveri flow eastwards and drain into the Bay of Bengal.

Answer 2

because the altitude in the west is average 900 to 1700 and at east it is only 600m , that is why the rivers flow in east at peninsular region.
