Two concentric conducting shells a and b are of radii R and 2R. A charge +q is centred at their center. Shell b is then earthed and a is given charge q. Find the charge on outer surfaces oboth shells.
Ans) THE charge on outer surface of A will be 2q and outer surface of B will be zero due to earthing charge on b will flow to earth.
With the help of relevant diagrams, define the following terms: (i) Pulse-position modulation (PPM) (i) Pulse-duration modulation (PPM)
For an object moving in uniform circular motion, the direction of the instantaneous acceleration vector is: w) tangent to the path of motion x) equal to zero y)
When we move from a positive charge towards an equal negative charge along the line joining the two then initially potential reduces in magnitude and at centre changes into zero, b
A steam turbine takes in saturated steam at 300 C and outputs steam at 4 bar. If the efficiency of the turbine is 65%, calculate: a. The final composition (vapor vs. Liquid) of
How can ultrasonic waves be detected Kundt’s tube method? Ultrasonic waves can be detected by Kundt’s tube. There at the nodes, lycopodium powder collects into the form of heap
in a uniform electric field, the potential is 10v at the origin and 8v at each of the points (1,0,0),(0,1,0) and (0,0,1).Find the potential at the point (1,1,1).

Explain the Natural Frequencies and Resonance Standing waves occur when the waves, like those in a vibrating piece of rope, are repeating so that there are places on the rope t
Hi i am doing research right now on anti-matter. I am just wondering if it is present in the human body?
If W is atomic weight and N is the atomic number of an element, then: (1) Number of e -1 = W- N (2) Number of 0 n 1 = W- N (3) Number of 1 H 1 = W-N (4) Number of 0
