Acharge of 7.00 mc is placed at opposite corners corner of a square 0.100 m on a side and a charge of -7.00 mc is placed at other opposite corners. determine the magnitude and direction of the force on right lower corner. explain.

4.03\times10^{7}N[/tex], 135°

Explanation:

charge, q = 7 mC = 0.007 C

charge, - q = - 7 mC = - 0.007 C

d = 0.1 m

Let the force on charge placed at C due to charge placed at D is FD.

The direction of FD is along C to D.

Let the force on charge placed at C due to charge placed at B is FB.

The direction of FB is along C to B.

Let the force on charge placed at C due to charge placed at A is FA.

The direction of FA is along A to C.

The net force along +X axis

The net force along +Y axis

The resultant force is given by

The angle from x axis is Ф

tan Ф = - 1

Ф = -45°

Angle from + X axis is 180° - 45° = 135°

no simpler subs form complex ones. synthesise = make

the order for strong to weak forces such as

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force

the fundamental forces are those forces that act between to objects or element to make interactions. there are four types of fundamental forces such as strong and weak nuclear forces (due to protons and electrons), electromagnetic force (due to the motion of electrons) and gravitational force (due to orbital movement of the planet). if these forces are arranged on the basis of their maximum strength then the order is

strong nuclear force → electromegnetic force → weak nuclear force → gravitational force
