Question 1
A liquid drop having 6 excess electrons is kept stationary under a uniform electric field of The density of liquid is The radius of the drop is (neglect buoyancy).
Question 2
A point charge q is placed at origin. Let , and be the electric field at three points A(1, 2, 3), B(1, 1, –1) and C(2, 2, 2) due to charge q. Then
[i]
[ii]
select the correct alternative
Question 3
Two identical point charges are placed at a separation of l. P is a point on the line joining the charges, at a distance x from any one charge. The field at P is E. E is plotted against x for values of x from close to zero to slightly less than l. Which of the following best represents the resulting curve?
Question 4
A charged particle of charge q and mass m is released from rest in an uniform electric field E . Neglecting the effect of gravity, the kinetic energy of the charged particle after time 't' seconds is
Question 5
An equilateral triangle wire frame of side L having 3 point charges at its vertices is kept in x-y plane as shown. Component of electric field due to the configuration in z direction at (0, 0, L) is [origin is centroid of triangle]
