Answer:
T' = 2T
Explanation:
The time period of a simple pendulum is given by the relation as follows :
l is length of the pendulum
g is acceleration due to gravity
If the length is increased four time, new length is l' = 4l
So,
New time period is :
So, the new time period is 2 times of the initial time period.
Answer:
6
Explanation:
Number of lines emanate from + 5 micro coulomb is 15 .
They terminates at negative charges that means at - 3 micro coulomb and - 2 micro Coulomb.
the electric field lines terminates at - 3 micro Coulomb and - 2 micro Coulomb is in the ratio of 3 : 2.
So the lines terminating at - 3 micro coulomb
=
So the lines terminating at - 2 micro coulomb
=
So, the number of filed lines terminates at - 2 micro Coulomb are 6.
