Dear Shivam

Apply a pseudo force on pendulum. initially downward force was mg only now downward  force will be mg+ma. as peudo force acts opposite to the direction of accelerating frame.

now just replace g by g+a called geffective in the expression of time period. so it wont die instantly but time period will be reduced as g comes in the denominator

All the best.
