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

zmey [24]

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.

God is with you!!!

A car enters a freeway with a speed of 6.5 m/s and accelerates to a speed of 24 m/s in 3.5 min. How far does the car travel whil

Vesna [10]

Explanation:

Using Equations of Motion :

(1) v = u + at

24 = 6.5 + a * 210

a (Acceleration) = 0.083 m/s^2

(2) v^2 = u^2 + 2aS

S = 576 - 42.25 / 0.166

S (Distance travelled) = 3215.3 m 

(Option A seems a typo since the answer is 3215.3 m)

A jet airliner moving initially at 612 mph (with respect to the ground) to the east moves into a region where the wind is blowin

Ganezh [65]

Answer:

966.22 mph

Explanation:

Velocity of plane with respect to wind (Vp,w)= 612 mph east

velocity of wind with respect to ground, (Vw,g) = 362 mph at 15° North of

east

Write the velocities in vector form

$V_{p,w}=612\widehat{i}$

$V_{w,g}=362\left ( Cos15\widehat{i}+Sin15\widehat{j} \right )= 349.67\widehat{i}+93.69\widehat{j}$

Use the formula for the relative velocity

$V_{p,w}=V_{p,g}-V_{w,g}$

Where, V(p,w) is the velocity of plane with respect to wind

V(p,g) is the velocity of plane with respect to ground

V(w,g) is the velocity of wind with respect to ground

So, $V_{p,g}=V_{p,w}+V_{w,g}$

$V_{p,g}=\left ( 612+349.67 \right )\widehat{i}+93.69\widehat{j}$

$V_{p,g}=961.67\widehat{i}+93.69\widehat{j}$

Magnitude of velocity of lane with respect to ground

$V_{p,g} = \sqrt{961.67^{2}+93.69^{2}}$

V(p,g) = 966.22 mph
