An alpha particle (charge = +2.0e) is sent at high speed toward a gold nucleus (charge = +79e). What is the electric force actin

umka2103 [35]

Answer:

F = 91.27 N

Explanation:

Parameters given:

Charge of alpha particle, q = +2.0e = $2.0 * 1.60217662 * 10^{-19}$ = $3.204 * 10^{-19} C$

Charge of gold nucleus, Q = +79e = $79 * 1.60217662 * 10^{-19}$ = $1.266 * 10^{-17} C$

Distance between the alpha particle and gold nucleus, r = $2.0 * 10^{-14} m$

Electric force is given as:

F = $\frac{kqQ}{r^2}$

where k = Coulomb's constant

Therefore:

$F = \frac{9 * 10^9 * 3.204 * 10^{-19} * 1.266 * 10^{-17}}{(2.0 * 10^{-14})^2} \\\\\\F = 91.27 N$

The electric force acting on the alpha particle when the alpha particle is $2.0 * 10^{-14} m$ from the gold nucleus is 91.27 N.

A 60.-kilogram physics student would weigh 1560

rosijanka [135]

Answer:

26m/s²

Explanation:

Given parameters:

Mass of the student = 60kg

Weight = 1560N

Unknown:

Acceleration due to gravity = ?

Solution:

Weight is a force on a body due to gravity;

Weight = mass x gravity

Insert the given parameters and solve;

1560 = 60 x gravity

Gravity = $\frac{1560}{60}$ = 26m/s²
