the top most expressions are important and the last expression is what I am getting this is one of the step of a problem in the book...

Homework Statement 6(2)^(n-2) +1 then summation of above equation will be 6(2)^(n-1) + n + 2 can you please tell me how this equaton came from the first equation? The Attempt at a Solution the later formula is correct summation of the former because it may look that the...

i got it thank you for your help

Prove that n^n (is less than or equal to) 1*3*5...(2n-1).Where n is any natural no. Homework Statement Prove that n^n (is less than or equal to) 1*3*5...(2n-1) n^n ≥ 1*3*5...(2n-1) .Where n is any natural number.I think Arithmetic or Geometric progression is used (A.P.>G.P.) The...

I was sorry for that. Thank you very much.

Homework Statement A biconvex symmetrical lens is cut in two halves and placed as shown in figure. if a point object is placed in the left how many images will be formed options - (a) Two images (b) Three images Homework Equations The Attempt at a Solution As I...

Is there any rule of solving problems, having some values very small for example ------------- if current in the circuit by a battery (of EMF= and internal resistance=r) =ε/r+R R=external load resistance if r is very small as compared to R , can we write it as =ε/R...

Thank you very much, I got it:smile:

What will be the total electric potential energy of two concentric spheres. Will it be = [P.E. of Inner sphere] + [ P.E. of Outer sphere] + [ Energy required to bring outer sphere from infinity to the present position(i.e. position concentric to inner sphere) ] OR it Will...

Thank you very much.

Is the discriminant, of the quadratic equations, the difference between the two roots? Or is it a special case?

Thank you very much I got it.:smile:

how potential energy of electric dipole perpendicular to electric field is zero in this situation the torque is maximum so how P.E. can be zero please help

Thank you very much.
