Question

Compute the ratio of the gravitational force and electrostatic force between an electron (mass =9.1×10^-31kg) and a proton(mass 1.7×10^27kg).Given e=1.6×10^-19 C. G=6.67×10^-11 Nm^2/kg^2. ANSWER ONLY IF YOU KNOW !!​

Answer 1

$\bold {\huge {Your ~answer :-}}$

⇒4.47 × 10^(-40)

════════════════════

↪Actually welcome to the concept of Electrostatic Force and mixture of Gravitational force

GIVEN—

The gravitational force : Electric force mass(mc = 9.1 × 10¯³¹ kg

proton of mass (mp) = 1.7 × 10¯²⁷ kg

e = 1.6 × 10¯¹⁹ C

G= 6.67 × 10¯¹¹ Nm²/ kg²

Mass of electron=9.1 × 10¯³¹ kg value given in the question is wrong.

Let us assume electron and proton are placed with separation distance metre.

Gravitational force Fg

Fg = G. (mp×me) /r²

On putting

Fg =

$= \frac{6.67 \times 9.1 \times 1.7}{r {}^{2} } 10^{ - 69}$

Simillarly

Electrostatic force Fe

Fe

$= \frac{9 \times {10}^{9} \times 1.6 \times 1.6}{ {r}^{2} } \times 10 {}^{ - 38}$

∴Therefore

Fg/Fe = 4.47 × 10^(-40)

Answer 2

Answer:

you answered my last question wrong you had forgotten to change the length in Y. don't worry I had got that question
