A charged cloud system produces an electric field in the air near the Earth's surface. A particle of charge -2.6 10-9 C is acted on by a downward electrostatic force of 3.0 ✕ 10-6 N when placed in this field.

(a) What is the magnitude of the electric field?

(b) What are the magnitude and direction of the electrostatic force Fel exerted on a proton placed in this field?

(c) What is the magnitude of the gravitational force Fg on the proton?

(d) What is the ratio Fel / Fg in this case?

a) E = 1153.85 N/C

b) Fel = 1.846*10⁻¹⁶N

A proton placed in this field will experience an upward force.

c) Fg = 1.638*10⁻²⁶N

d) Fel / Fg = 1.126*10¹⁰

Explanation:

Given

q = -2.6*10⁻⁹ C

Fel = 3.0*10⁻⁶ N

a) We can use the formula

Fel = q*E ⇒ E = Fel/q

⇒ E = (3.0*10⁻⁶ N)/(2.6*10⁻⁹ C) = 1153.85 N/C

b) We apply the same equation using E = 1153.85 N/C:

Fel = q*E  

⇒ Fel = (1.6*10⁻¹⁹C)*(1153.85 N/C) = 1.846*10⁻¹⁶N

A proton placed in this field will experience an upward force.

c) We use the formula

Fg = mp*g

⇒ Fg = (1.67*10⁻²⁷Kg)*(9.81 m/s²) = 1.638*10⁻²⁶N

d) Ratio: Fel / Fg = (1.846*10⁻¹⁶N)/(1.638*10⁻²⁶N) = 1.126*10¹⁰

the correct answer is b

hail is a solid form of precipitation composed of large, layered ice particles called pellets that often have spherical shapes. this phenomenon occurs during thunderstorms in the could type known as cumulus

hope this you out ^w^
