Answer:
0.0316 m
Explanation:
Wok done = Energy change
Work done on the spring = Energy change of the block
Elastic Potential stored = Kinetic energy of the block
x =
x =
x = 0.0316 m
k = spring constant
m = mass of block
v = velocity of the block
x = compression of spring
I think the airplan flies in same speed 400

Answer:
Electric field due to two charges is given as
Explanation:
As we know that two charges are opposite in nature
So the electric field at the mid point of two charges will add together
so the net field is given as
now we have
now we have
