Two 53.0 x 10^-9 C point charges are located on the x axis. One is at x = 0.35 m, and the other at x = - 0.35 m.

a) A third identical charge is placed on the y axis at y = 0.35 m. Find the magnitude of the force acting on this third charge? Answer in Newtons.

b) Now the third identical charge is placed on the y axis at y = 2 x 0.35 m. Find the magnitude of the force acting on this third charge? Answer in Newtons.

Four charges are placed at the corners of a square. The side of the square is a = 0.30 m.

a) If the charge are identical and positive q = 21.0 x 10^-9 C what would be the magnitude of the force acting on each of the charges? Answer in Newtons.

b) We change the charges by q₁ = 21.0 x 10^-9 C, q₂ = 11.0 x 10^-9 C, q₃ = -12.0 x 10^-9 C, q₄ = -31.0 x 10^-9 C. What would be the magnitude of the force acting on charge q₃? Answer in Newtons.

c) We place the same charges at the corners of a rectangle of sides a and b (instead of a square). If b=2a/3 what would be the magnitude of the force acting on charge q₃? Answer in units of Newtons.

Expert Solution

Two 53.0 x 10^-9 C point charges are located on the x axis. One is at x = 0.35 m, and the other at x = - 0.35 m.

a) A third identical charge is placed on the y axis at y = 0.35 m. Find the magnitude of the force acting on this third charge? Answer in Newtons.here r = 0.494 m

F = kqq(1/0.494² + 1/0.494²)

= 3.90 *10^-6 N

b) Now the third identical c harge is placed on the y axis at y = 2 x 0.35 m.

here r = 0.782

F = kqq(1/0.782² + 1/0.782²)

F = 1.557 *10^-6 N

b.

Four charges are placed at the corners of a square. The side of the square is a = 0.30 m.

a) If the charge are identical and positive q = 21.0 x 10^-9 C the magnitude of the force acting on each of the charges

F = kq1q2/r^2

F = 9*10⁹(21.0 x 10^-9)²(1/.3² +1/.3² + 1/.424²)

F = 1.102*10^-6 N

b) We change the charges by q₁ = 21.0 x 10^-9 C, q₂ = 11.0 x 10^-9 C, q₃ = -12.0 x 10^-9 C, q₄ = -31.0 x 10^-9 C. the magnitude of the force acting on charge q₃

F = k* -11.0 x 10^-9*10^-9( 21.0/.424² + 12/.3² -31/.3²)

F = 9.33*10^-6 N

3. Two 2.20-?C point charges are located on the x axis. One is at x = 1.57 m, and the other at x = -1.57 m.

the magnitude of the electric field on the y axis at y = 0.530 m

E = kq/r^2 where r = 1.657 m

E = 9*10^-9*2.2*10^-6(1/1.657² -1/1.657²)

E = 0
