Question

A TRAIN PASSES AN ELECTRIC POLE IN 10S AND A BRIDGE OF THE SAM LENGTH AS THE TRAIN IN 20S. AMONG THE FOLLOWING,THE CORRECT STATEMENT IS

Answer 1

Answer:

a) It is moving with uniform velocity

Explanation:

Let the length of train is x  

Given time for electric pole is 10 second

                    Bridge of same length 20 sec,

Let assume a electric pole at the both end of the bridge.

                    time for that 20 sec.

so total length train+pool = 2x

So, for covering 2x time is 2*10=20 sec.

Hence, it is moving with constant velocity.

Hope this helps!
