Answer:
The magnitude of acceleration is reduced.
Explanation:
Force is defined as push or pull
The force is said to be<em> balance force </em>if the force are equal in size but opposite in direction. ie the object does not move or move with constant speed.
The force are to be<em> unbalanced force </em>if the force cause change in motion. ie the object has force greater than zero and has acceleration.
According to <em>Newton second law of motion </em>, acceleration depends on force acting on the object and mass of object.
F=ma
a=
When unbalanced force act on the mass of object it reduces magnitude of acceleration without changing the direction.
Explanation:
(a) Formula to calculate the density is as follows.
=
=
Now, calculate the charge as follows.
=
= C
or, = 101.06 nC
(b) For r = 6.50 cm, the value of charge will be calculated as follows.
=
= 7.454
