When an electron moves 2.5 m in the direction of an electric field, the change in electrical potential energy of the electron is

anygoal [31]

In the field of electromagnetism, when two charged plates that are situated opposite to each other by a certain distance, it forms an energy called the electric field. This energy is due to the difference in potential energy with respect to distance. Thus,

E = V/d

However, the voltage in volts is energy per coulomb. Thus,
V = (8x10-17 J/electron)*(1electron/1.60218x10^-19 C)
V = 499.32 volts

Therefore,

E = 499.32 volts /2.5 m
E = 199.73 N/C

The electric field that caused the change in potential energy is equal to 199.73 Newtons per Coulomb.

What is the acceleration of a boat if the resultant force on it is 4000 N and its mass is 1240 kg

Marrrta [24]

Answer:

The acceleration of a boat if the resultant force on it is 4000 N and its mass is 1240 kg is 3.2 m/s².

Explanation:

Given

Force F = 4000 N

Mass m = 1240 kg

To determine

Acceleration a = ?

Important Tip:

The acceleration of a boat can be found using the formula F = ma

Using the formula

$F = ma$

where

F is the force (N)

m is the mass (kg)

a is the acceleration (m/s²)

now substituting F = 4000, m = 1240 in the formula

$F = ma$

$4000\:=\:1240\:\times a$

Switch sides

$1240a=4000$

Divide both sides by 1240

$\frac{1240a}{1240}=\frac{4000}{1240}$

Simplify

$a=\frac{100}{31}$

$a=3.2$ m/s²

Therefore, the acceleration of a boat if the resultant force on it is 4000 N and its mass is 1240 kg is 3.2 m/s².
