1) EA = 0
2)(QA/RA) = (QB/RQB)
=>RA > RB
=>QA > QB
3)σ R = V
4) E = σ/(2 Eo
4) A spherical metal shell A of radius RA and a solid metal sphere B of radius RB(< RA) are kept far apart and each is given charge ’+Q’. Now they are connected by a thin metal wire.Then
Answer is:
((σA)/(σB)) = ((RA)/(RB))

Answer is:
((Ne2)/(mEo))1/2
Explanation:
ω = θ/T = T-1
=>D.f. of ((Ne2)/(mEo))1/2 = (((1/L3)*(I2T2)*(ML3T-2))/(M*(I2T2)))
=> D.f = T-1
Answer is:
600nm
Explanation:
ω = 2π n
=> n= (ω)/(2π)
=>c=nλ
=>λ = c/n = (c2π)/(ω) = 66nm
Answer is:
Inertia
Explanation:
Newton's first law of motion - sometimes referred to as the law of inertia. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
Answer is:
By Negative ions
Explanation:
In the process of the reaction, electrons can be transferred from the zinc to the copper through an electrically conducting path as a useful electric current. An electrochemical cell can be created by placing metallic electrodes into an electrolyte where a chemical reaction either uses or generates an electric current
