the time period will remain the same.. the bob will do small oscillations but we know that \[T=2\Pi \sqrt{l/g}\] so in this eqn.there is no amplitude..therefore T is not related to the amplitude... hence time period remains same..

T resembles the time period of the bob.. by the way which text book are you studying?

Time period will decrease, since new weight relative to train coach will be bigger: mg* with \(\vec {g*}=\vec g-\vec a \) and \(g^*=\sqrt{g^2+a^2}\) \(T^*=2\pi \sqrt{l/g^*}\)
