A short electric dipole is placed at the origin of the Co-ordinate system with its dipole moment P along y direction. Give answer to following questions for points which are at large distance r from the origini in x-y plane. [r is large compared to length of the dipole] (a). Find maximum value of x component of electric field at a piont that is at r_(0) distance from the origin (b). Prove that (for 0 lt theta lt 90^(@) ) all the points, where electric field due to the di8pole is parallel to x-axis, fall on a straight line, find the slope of the line.

A graph of the x-component of the electric field as a function of x in a region of space is shown in figure. The y- and z-components of the electric field are zero in this region. If the electric potential is 10 V at the origin, then the potential at x = 2.0 m is

Magnetic field in a space is given as B = -(B_(o)x)/(R )hat(k) . A circular ring of radius R having current I lies in the space with centre at origin as shown in the figure. Find the magnitude of net magnetic force acting on the circular ring due to the magnetic field.

A boy standing on the top of a tower of height 54 ft. throws a packet with a speed of 20 ft/s directly aiming towards his friend standing on the ground at a distance of 72 ft from the foot of the tower. The packet falls short of the person on the ground by x xx(16)/(3) ft. The value of x is

A short bar magnet of magnetic moment 1.5 Am^2 is placed along x-axis at origin. If the magnetic field along line joining origin to point [P(2 sqrt3,2,0)] m is [{sqrt(n) *10^-7} /128 (T)] , Then n should be

A short magnetic dipole when placed at origin with its dipole moment oriented along x-axis , the magnetic field at the point (a,0) is vecB . What will be the magnetic field at the above point , if another identical dipole is also placed at origin with its dipole moment oriented along y-axis ?

If P(x,y,z) is a point in space at a distance r from the origin O, then the direction cosines of the line OP are
