For cation<span> and its original </span>atom<span>, the </span>cation<span> is smaller than its original </span>atom<span> in </span>size<span>. Ex. Radius of Fe2+ is smaller than radius of Fe. Reason is there is less electrons in the </span>cation<span>, making the shielding effect from the electrons smaller while the attraction force from the nucleus remains the same.</span>

The proton (positive charge) shall be closer to the charge with the lower magnitude which is at the orgin.

The proton also shall be out of the interval between the two charges so that the pull of one charge cancels with the push of the other.

The region at which those conditions happen is to the left of the origin.

In that case the forces over the proton shall be:

k* (2.4 nC) * p / (x^2) - k*(4.8 nC) * p /( 1.3 + x)^2 = 0

where p is the charge of the proton.

You can simplify k and p:

2.4 / x^2 - 4.8 / (1.3 + x)^2 = 0

You can also simplify by 2.4

1/ x^2 - 2 / (1.3 + x)^2 = 0

(1.3+x)^2 - 2x^2 = 0

1.69 + 2.6x + x^2 - 2x^2 = 0

1.69 + 2.6x - x^2 = 0

x^2 -2.6x - 1.69 =0

Solve using the quadratic formula: x = 3.14 (use only the positive value)

That is the proton shall be place 3.14 units to the left of the origin (positive charge)

True. Bc a physical property is the appearance. A chemical property is like flammability. Hope this helps!

**Explanation:**

**Given that,**

Mass of disk = 1.2 kg

Radius = 0.07 m

Radius of rod = 0.11 m

Mass of small disk = 0.5 kg

Force = 29 N

Time t = 0.022 s

Distance d= 0.039 m

**(I). We need to calculate the speed of the apparatus**

**Using work energy theorem**

Where, m = total mass

v = velocity

F = force

d = distance

Put the value into the formula

**(b). We need to calculate the angular speed of the apparatus**

**Using formula of torque**

**We need to calculate the angular speed of the apparatus**

**Using equation of angular motion**

Put the value into the formula

**(c). We need to calculate the angular speed of the apparatus**

**Using equation of angular motion**

Put the value into the formula

**Hence, This is required equation. **

**Answer:**

A constant net force acts on an object. Describe its motion. the object is moving with constant acceleration. Same net force is applied to two different objects but the second object has twice the mass
