1. A negatively charged ebomite rod repels a suspended object.can we conclude that the object is negatively charged?

Calculate the Directional derivative of Scalar field f(x,y,z)= x²+yz+z² at p (1,2,1) along n normal unit vector = 1/3 ( 2 i certisian unit vector- j certisian unit vector+ 2k certisian unit vector)

calculate the directional derivative of scalar field f(x,y,z)=(x ²+yz+z²)at (1,2,1) along n^=1/3(2i-j+k^)

shows an arrangement of four charged particles, with angle θ = 30.0° and 

distance d = 2.00 cm. Particle 2 has charge q2 = +8.00 × 10-19 C; particles 3 and 4 have charges q3

= q4 = -1.60 × 10-19 C. (a) What is distance D between the origin and particle 2 if the net 

electrostatic force on particle 1 due to the other particles is zero? (b) If particles 3 and 4 were 

moved closer to the x axis but maintained their symmetry about that axis, would the required 

value of D be greater than, less than, or the same as in part (a)?

How much force is repelled by two pieces of copper, each weighing 1 g, located at a distance of 100 km, if all the atoms of one and the other piece are "taken away" by electrons, ie all atoms in the samples are completely ionized ?, 

The max magnetic field strength of an electromagnetic field is 5 x 10^-6 T. Calculate the maximum electric field strength if the wave is travelling in a medium in which the speed of the wave is 0.75c.

1.What is the max electric field strength in an electromagnetic wave that has a maximum magnetic field strength of 5 x 10^-4 T (about 10mtimes the Earth's)?
