PLEASE ANSWER QUESTIONS WITH FULL STEPS. THANK YOU!

1) A -2.0 uC charge experiences a 6.0 I hat-N electric force in a certain electric field.

A) what force would a proton experience in the same field?

2)The dipole moment of the water molecule is 6.2 X 10^-30 C*m.

A) What would be the separation distance if the molecule consisted of charges +- e? Note: the effective charge is actually less because electrons are shared by the oxygen and hydrogen atoms.

3) The electric field 23 cm from a long wire carrying a uniform line charge denisty is 2.4kN/c.

A) What will be the field strength 42cm from the wire?

Explanation / Answer

1) A -2.0 uC charge experiences a 6.0 I hat-N electric force in a certain electric field.

A) what force would a proton experience in the same field?

E = F / q = 6 / -2 x 10-6 = -3 x 106 N/C

Fp = E q = (-3 x 106 N/C) (1.6 x 10-19 C) = -4.8 x 10-13 N

2)The dipole moment of the water molecule is 6.2 X 10^-30 C*m.

A) What would be the separation distance if the molecule consisted of charges +- e? Note: the effective charge is actually less because electrons are shared by the oxygen and hydrogen atoms.

dipolemoment = 2l * q

2l = dipolemoment / q

= 6.2 X 10-30 C*m / 1.6 x 10-19C

= 3.875 x 10-11 m

3) The electric field 23 cm from a long wire carrying a uniform line charge denisty is 2.4kN/c.

A) What will be the field strength 42cm from the wire?

E 1 / E2 = R2 / R1

E2 = E1 R1 / R2

= 2400 * 23 / 42

= 1314.28 N/C

= 1.314 kN/C
