Thanks for the reply. But, I didn't get you. I am familiar with that formula. I understand that we use that formula to substitute ##\cfrac{|V_2|}{|V_1|} = \cfrac{1}{\sqrt{2}}## but how does it explain the ##\cfrac{1}{2\sqrt{2}}## part ?
Thanks again.

For first problem:
##\cfrac{|V_2|}{|V_1|} = \cfrac{1}{\sqrt{4+(\omega RC)^2}}##
For second problem:
##\cfrac{|V_2|}{|V_1|} = \cfrac{\sqrt{1+(\omega RC)^2}}{\sqrt{4 + (\omega RC)^2}}##
I have to calculate half power frequency for both...
Thanks for the reply. I am also stuck with what the question expects me to do. As for the force in x-direction, can you please tell me which other force will act ?

A mass m hangs on a spring of constant k. In the position of static equilibrium the length of the spring is l. If the mass is drawn sideways and then released,the ensuing motion will be a combination of (a) pendulum swings and (b) extension and compression of the spring...
Hi!
Whenever you face problems with probability questions of this sort, try to build a venn diagram (like the one I have attached).
Use the venn diagram to calculate n(A∩B) and then Pr(A∩B). Then, you will have to use your third formula because here a condition is given ---> he/she has a job...
Thanks for the reply.
Net moment of inertia, ##I_{net} = I_{1} + I_{2} = \cfrac{1}{2} MR^2 + (\cfrac{1}{2}MR^2 + Ml^2)##
##\implies I_{net} = MR^2 + Ml^2##
Plugging in the values in the formula:
##\omega = \sqrt{\cfrac{mgl}{I}} = \sqrt{\cfrac{(2M)g(\cfrac{l}{2})}{MR^2 + Ml^2}}##
## \implies...
