If P = 4.00î + 3.00k, P · Q = 17.0, and P ✕ Q = −6.00ĵ, determine the vector Q.
Butoxors [25]

let the vector Q is given as

\vec Q = a\hat i + b\hat j + c\hat k

given that

P X Q = -6\hat j

here we know that

P = 4\hat i + 3 \hatk

now by above equation

(4\hat i + 3\hat k) X (a\hat i + b\hat j + c\hat k) = - 6\hat j

4b\hat k - 4c\hat j + 3a\hat j - 3b\hat i = - 6\hat j

so by comparing both sides

b = 0

4c - 3a = 6

also we know that

a^2 + b^2 + c^2 = 17^2

a^2 + 0 + (1.5 + 0.75a)^2 = 289

by solving above equation

a = 12.85 and c = 11.14

so the vector Q is given as

Q = 12.85\hat i + 11.14\hat k

Two spheres carry a charge of 1x10^-7 C. Their centers are separated by 0.7m. Calculate the magnitude of the force between the t
Drupady [299]

We have that the  force between  the two charged objects is mathematically given as

F=2.349N

<h3>Magnitude of the force between  two charged objects.</h3>

Question Parameters:

Two spheres carry a charge of 1x10^-7 C.

Their centers are <u>separated</u> by 0.7m.

Generally the equation for the Force  is mathematically given as

F=\frac{q1q2}{4*\pi e*r}

Therefore

F=\frac{(1e-7)^2}{9e9*0.7}

F=2.349N
