Since the electric field between the plates is constant
so we can say the relation between potential difference and electric field is given by

here from above relation we can say that is electric field is kept constant then potential difference is directly proportional to the distance between the plates
so here we will say that if the distance between the plates is decreased then the potential difference between the plates will also decreases
So correct answer will be
<u>a) decrease </u>

The time taken is 50 s
Explanation:
For a body moving in uniform motion (= at constant velocity), the velocity of the body is given by:

where
v is the velocity
d is the distance covered
t is the time taken
In this problem, we have a bird travelling with uniform motion. We know that:
v = 8 m/s is the velocity of the bird
d = 400 m is the distance travelled
Solving for t, we find the time the bird needs to cover this distance:
