If I were to design a radiation detector to detect electron radiations , but in the process proton ,alpha and beta radiations are also being detected , then how can I implement a filtering technique to filter the rest out? Mass based filtering can be used i suppose?

IF it was DC, won't we consider a time variant state?

1. A Wheat stone bridge resembling setup is given with two parallel branches , the 1st containing an Inductor of Inductance L1 and resistance R1 in series with a resistor R2. The second branch consists of inductor with inductance L2 and resistance R3 in series with a resistor R4. The branches...

[tan(2x) * tan(3x) - 1]/ tan(3x)=0 -[tan(2x)+ tan(3x) / tan(5x)tan(3x)]=0 tan(2x)=-tan(3x) following this: tan(a+b) = tan(a) + tan (b) / 1-tan(a)tan(b) tan(a)tan(b)-1 = 1[ tan(a)+ tan(b)/ tan(a+b)] And If i am wrong somewhere correct me.

So Maxwell could see this through his equations?

But , that seems a bit confusing. I don't get that level of mathematics.

What if i was traveling in a car with an e- with me. W.r.t to a positive charge at rest , it would seem accelerating to me i.e. it would have a magnetic field but acc. to a person on the ground it would just have an electric field. If there were a car moving relative to me , the person would...

Hey! I just found out that its an ex Physics olympiad problem. The dust configuration remains constant , won't move in. So we can do this using the potential energy concept for the sphere's i.e. they would try and reduce their respective energies.

can some1 tell me the final answer so that i can confirm it? i do not have the answer.

@ rl.bhat why 0 to pi?? why not o to 2pi? @alphysicist yes i took it from the left actually and after pi/2 cos which change the sign as it will be pi-theta.

Yes , they are simply voids. The Dust particles are distributed uniformly and there are two nearby spherical voids.

r + r(1-cos$) ?

we knw tan(A+B)=tanA+ tanB/ 1-tanAtanB hence tanAtanB-1= -(tan A+tanB/tan(A+B)) tan2xtan3x-1/tan3x= -tan2x -tan3x / tan5x hence solutions can be generated from tan2x=-tan3x. hope u knw the general formula for the solns of that. and rejecting all solns where tan5x=0. :)

Thats the main trouble , i am not able to find a way to get the dependence of B on $ because B is just dependent on distance from the wire. And i have already judged the directions , its the magnitude that bothers me.

Hey thanks that cleared a lot up.
