A proton is at the origin. One electron is at the point (2m, 4m)

Physics
1 answer:
Nimfa-mama [501]3 years ago
5 0

Answer:

Correct answer:  F = 0 N

Explanation:

All three elementary charges are in the same straight line or direction.

Since the electron and proton are opposite charged, their force is attractive and directed toward the electron.

The forces are of the same intensity-magnitude and opposite directions and are canceled, so the resultant- net force by which the electrons act on the proton is zero.

Explanation:

Maggie using her cat in the experiment to test for intelligence gives the cat an unfair advantage, her experimental results will be biased.

A brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 780 N on him. The
stich3 [128]

Answer:

f = 556.4 N

Explanation:

Mass of the losing player with its all equipment is given as

M = 86 kg

Net force applied on him by another player is given as

F = 780 N

also we know that acceleration of the losing player is given as

a = 2.6 m/s^2

now by Newton's 2nd law we will have

F - f = ma

780 - f = 86(2.6)

780 - f = 223.6

f = 556.4 N

What is the mass of an object that has an acceleration of 2.63m/s2 when a unbalanced force of 112N is applied to it?
exis [7]

Answer:

42.58kg

Explanation:

By Newton's second law, F = ma.

F is the force being applied, in this case 112N. a is the acceleration, in this case 2.63 m/s^2.

Thus, with some simple algebraic manipulation, we get the mass to equal:

m = F/a = 112N / 2.63 m/s^2 = 42.58kg
