Answer:
The electrical force between two balloons is 67.5N.
Explanation:
There are two charged balloons, let's say a and b.
The charge on the balloon a = C
The charge on the balloon b = C
Both balloons are 1 cm apart; it means that the distance<em> r</em> between the balloon a and the balloon b is 0.01 m (since 1 cm = 0.01 m).
We need to find the electrical force between them. By using the Coulomb's law, the magnitude of the electrical force between both the balloon is given as follows:
--- (A)
Where,
k = Coulomb's constant = =
Plug all the values in the equation (A):
Hence, the electrical force between two balloons is 67.5N (three significant figures).
Answer:
<em>the centripetal acceleration will now be four times its initial value</em>
Explanation:
v=velocity
a=centripetal acceleration
r=radius to the center
take note tat a centripetal force is the force tat is needed to keep a body moving along a circular path
centripetal force is given by f=mv^2/r
a=v^2/r
v=v
wen v is doubled , we ave
2v
substituting into the previous equation of centripetal force
a=(/r
a=4^{2}/(r)
from the equation, is can be discovered that the centripetal acceleration will now be four times its initial value
