Explanation:
work done=force ×distance
force=Mass ×accelleration
work done=50×8×0.4
=160J

Because they are conducting, when you bring them together the charge is split equally among the two spheres (because they have the same radius the amount of charge is also equal). Now they will repel each other because of the net charge on each with the same polarity.
Answer:
160 m
Explanation:
distance covered in 1 s = 8 m
therefore, distance covered in 20 s = 8 * 20 m = 160 m
K.e=1/2mv²
K.e=1/2 2(5)²
K.e=1/2 2×25
K.e=50/2
K.e=25J
Answer:
you can measure by scale beacause we dont no sorry i cant help u but u can ask me some other Q
