Answer:

doubled

Explanation:

<u>Step 1</u>. Linear momentum (p) = mass X velocity = mv

p = mv -----equation 1

<u>Step 2</u>. if the mass is now twice and speed is same

p = (2*m)v -----equation 2

solving equation 1 and 2 together,

p = mv = 2mv

p = 2

Therefore, its momentum is doubled

Two particles, one with charge -6.29 × 10^-6 C and one with charge 5.23 × 10^-6 C, are 0.0359 meters apart. What is the magnitud
navik [9.2K]

Answer:

Force, F = −229.72 N

Explanation:

Given that,

First charge particle, q_1=-6.29\times 10^{-6}\ C

Second charged particle, q_2=5.23\times 10^{-6}\ C

Distance between charges, d = 0.0359 m

The electric force between the two charged particles is given by :

F=k\dfrac{q_1q_2}{d^2}

F=9\times 10^9\times \dfrac{-6.29\times 10^{-6}\times 5.23\times 10^{-6}}{(0.0359)^2}

F = −229.72 N

So, the magnitude of force that one particle exerts on the other is 229.72 N. Hence, this is the required solution.

Newton’s Third Law:
olya-2409 [2.1K]

If one force acting in one direction is greater than the force acting in the opposite direction, the object will <u>move.</u>

<h3>What is Newton's third law of motion?</h3>

Newton's third law of motion state that every action has an equal and opposite reaction. It is an action-reaction principle. It stated that the force always exists in a pair.

Hence,if one force acting in one direction is greater than the force acting in the opposite direction, the object will <u>move.</u>
