Will also have low frequency
Answer:
1210 ohm
Explanation:
Given :
P=40 W
V=220 V
Now,

Therefore, resistance of bulb will be 1210 ohm
The electrostatic force between the two charges is

where q1 and q2 are the magnitudes of the two charges, and r the distance between them.
We can see from the formula that F is proportional to the product between the two charges:

so, if the magnitude of each charge is doubled, the new force will get a factor 4:

So, the new force will be 4 times the original force:
