Positive electric charge Q is distributed uniformly throughout the volume of an insulating sphere with radius R.From the express

AlladinOne [14]

Answer:

Vb = k Q / r r <R

Vb = k q / R³ (R² - r²) r >R

Explanation:

The electic potential is defined by

ΔV = - ∫ E .ds

We calculate the potential in the line of the electric pipe, therefore the scalar product reduces the algebraic product

VB - VA = - ∫ E dr

Let's substitute every equation they give us and we find out

r> R

Va = - ∫ (k Q / r²) dr

-Va = - k Q (- 1 / r)

We evaluate with it Va = 0 for r = infinity

Vb = k Q / r r <R

We perform the calculation of the power with the expression of the electric field that they give us

Vb = - int (kQ / R3 r) dr

We integrate and evaluate from the starting point r = R to the final point r <R

Vb = ∫kq / R³ r dr

Vb = k q / R³ (R² - r²)

This is the electric field in the whole space, the places of interest are r = 0, r = R and r = infinity

Consider a metal single crystal oriented such that the normal to the slip plane and slip direction are at angles of 60° and 35°,

Vedmedyk [2.9K]

Answer:

19.5324 MPa

Explanation:

Information provided

Angle between the normal to the slip plane with tensile axis, $\alpha=60^{o}
$

Angle by slip direction with tensile axis, $\beta=35^{o}$

Critical resolved shear stress, $\tau_{c}=8 MPa$

Applied stress $\sigma=12 MPa$

Shear stress at slip plane

$\tau=\sigma cos\alpha cos\beta$

$\tau=12cos60^{o}cos35^{o}=4.915 MPa$

$\tau$ hence crystal won’t yield

Applied stress, $\sigma$ for crystal to yield is given by

$\sigma=\frac {\tau_{c}}{cos\alpha cos\beta}$

$\sigma=\frac {8}{cos60cos35}=19.53239342 MPa$

$\sigma=19.5324 MPa
$

the electric field midway between two equal but opposite point charges is 573 n/c , and the distance between the charges is 16.0

saveliy_v [14]

The electric potential between the two charges is 91.68 V.

<h3>Electric potential between the two charges</h3>

The electric potential between the two charges is calculated as follows;

V = Ed

where;

V is electric potential
E is electric field
d is the distance of the charge

Substitute the given parameters and solve for electric potential,

V = 573 N/c x 0.16 m

V = 91.68 V

Thus, the electric potential between the two charges is 91.68 V.
