Answer:

\boxed{ \bold{ \sf{see \: below}}}

Explanation:

\boxed{ \bold{ \underline{ \huge{  \boxed{ \sf{ohm's \: law}}}}}}

The relation between current through a metallic conductor and potential difference across its ends was studied systematically by a German physicist , <u>George </u><u>Simon </u><u>Ohm </u> in <u>1</u><u>8</u><u>2</u><u>6</u><u> </u><u>AD </u>. This relation is now known as Ohm's law. It states that <u>the </u><u>electric </u><u>current </u><u>passing </u><u>through</u><u> </u><u>a </u><u>conductor </u><u>is </u><u>directly </u><u>proportional</u><u> </u><u>to </u><u>the </u><u>potential </u><u>difference</u><u> </u><u>across </u><u>its </u><u>two </u><u>ends </u><u>at </u><u>a </u><u>constant </u><u>physical </u><u>condition</u><u> </u><u>[</u><u> </u><u>Temperature</u><u> </u><u>,</u><u> </u><u>cross </u><u>-</u><u> </u><u>sectional </u><u>area </u><u>,</u><u> </u><u>length </u><u>,</u><u> </u><u>nature </u><u>of </u><u>material </u><u>etc </u><u>]</u>

Hope I helped!

Best regards!!

FIGURE 1 shows part of a mass spectrometer. The whole arrangement is in a vacuum. Negative ions of mass 2.84 x 10-20 kg and char
yuradex [85]

Yes, the ions can exit slit P without being deflected, if the electric field strength is 170.6 N/C

Explanation:

When the ions are inside the container, they are subjected to two forces, with directions opposite to each other:

  • The force due to the electric field, whose magnitude is F_E=qE, where q is the charge of the ion and E is the strength of the electric field
  • The force due to the magnetic field, whose magnitude is F_B=qvB, where v is the speed of the ions and B is the strength of the magnetic field

The ions will move straight and undeflected if the two forces are equal and opposite. By using Fleming Left Hand rule, we notice that the magnetic force on the (negative) ions point upward: this means that the electric field must be also upward (so that the electric force on the ions is downward). Then, the two forces are balanced if

F_E = F_B

which translates into

qE=qvB\\\rightarrow v = \frac{E}{B}

Therefore, if the speed of the ions is equal to this ratio, the ions will go undeflected.

We can even calculate the value of E at which this occurs. In fact, we know that the ions are earlier accelerated by a potential difference V=-3000 V, so we have that their kinetic energy is given by the change in electric potential energy:

qV=\frac{1}{2}mv^2

where

q=-2.0\cdot 10^{-19}C\\m=2.84\cdot 10^{-20}kg

Solving for v, the speed,

v=\sqrt{\frac{2qV}{m}}=\sqrt{\frac{2(-2.0\cdot 10^{-19})(-3000)}{2.84\cdot 10^{-20}}}=205.6 m/s

And since the magnetic field strength is

B = 0.83 T

The strength of the electric field must be

E=vB=(205.6 m/s)(0.83 T)=170.6 N/C

An object is attached to a hanging unstretched, ideal and massless spring and slowly lowered to its equilibrium position, a dist
Ad libitum [116K]

Answer:

10.6cm

Explanation:

We are given 5.3cm below the starting point (spring extension).

Therefore, to find static vertical equilibrium, we use the equation:

kx = mg

Where:

k = spring constant =

=mg/5.3 kg/s²

We are told the object was dropped from rest.

Therefore:

loss in potential energy = gain in spring p.e

Let's use the expression:

mgx = ½kx²

We are asked to find the stretch at maximum elongation x.

To find x, we make x subject of the formula.

Therefore, we have:

x = 2mg/k (after rearranging the equation above)

x = (2mg) / (mg/5.3)

x = 10.6cm
