A plane conductor with very large dimensions is charged such that surface charge density is 1.6xx10^(-2)C//m^(2) . The electric field intensity at a point near it if the conductor is in a medium of dielectric constant 5 is

A charged cylinder of radius 3 mm has surface density of charge 4muC//m^(2) . It is placed in a medium of dielectric constant 6.28. The electric intensity at a point at a distance of 1.5 M from its axis is

If L = 39.5 , Delta_(1) = 6 , Delta_(2) = 9 and c = 10 , then find the mode of the data .

In a class of 50 students, 23 speak English, 15 speak Hindi and 18 speak Punjabi. 3 speak only English and Hindi, 6 speak only Hindi and Punjabi and 6 speak only English and Punjabi. If 9 speak only English, then how many speak all the three? (a) 1 (b) 2 (c) 3 (d) 5

A charged particle of radius 5xx10^(-7)m is located in a horizontal electric field of intensity 6.28xx10^(5)Vm^(-1) . The surrounding medium has the coeffiecient of viscosity eta=1.6xx10^(5)Nsm^(-2) . The particle starts moving under the effect of electric field and finally attains a uniform horizontal speed of 0.02 ms^(-1) . Find the number of electrons on it. Assume gravity free space.

A galvanometer is used in laboratory for detecting the null point in electrical experiments . If , on passing a current of 6mA , it produces a deflection of 2^(@) , its figure of merit is close to :
