Electricity and Magnetism Answers

Please give answer :An object is enclosed within a metallic spherical shell having surface charge + q C. The object will carry charge – q .

In a triangle APC, AC =AB+BC, AB=BC=2cm.AP=4cm,PC=4cm, At point B BP is perpendicular to AC. Charges q1,q2,and q3 are placed at A, B, C respectively. And q1 =q2=-q3=2micro C. Determine the magnitude and the direction of the electric field at point P.

Is it true? The work done in taking a unit charge from one point to another in the electric field of a charge +Q C depends on the path followed by the charge.

Is it true when an object is enclosed within a metallic spherical shell having surface charge +qC. The object will carry charge -qC.

Obtain the directional derivative for a scalar field (x,y,z)=3x^2y-y^3z^2 at the point (1,-2,-1) in the direction i+j+k

Two charges, magnitude + 2 x 10-6 C each are 60cm apart. Find the magnitude of the force exerted by these charges on a third charge of magnitude + 4 x 10-6 C that is 50 cm away from each of the first two charges.

Is it true? The electric field associated with a plane electromagnetic wave is given by E=50 cos(wt-10πx)z bar V/m.its wavelength is 0.5m

Is the statement is true or false. Give reason. An electron moves in a magnetic field of 1T with velocity 5.0 x 10 raise power 5 m/s in the direction of the magnetic field. The magnitude of the force experienced by the electron is 9.5 x 10 raise power —14 N

A negatively charged particle is placed inside a spherical shell with positive charge distributed evenly on its surface. Draw the electric field lines at equilibrium state on the diagram
