Answer:

E=\dfrac{KQx}{(x^2+a^2)^{\frac{3}{2}}}

Step-by-step explanation:

Given that

Radius of ring=a

Distance of point P from center=x

Total charge=Q

We know that electric field is given by

E=\dfrac{KQcos\theta }{r^3}

Here electric field in two direction will be cancel out and only in one direction electric field will exits.

 cos\theta =\dfrac{x}{r}

r^2=x^2+a^2

E=\dfrac{KQx}{(x^2+a^2)^{\frac{3}{2}}}

If 3 to the power of x+1 = 81 and 81 to the power of x-y = 3 then what is the value of x and y?
fgiga [73]
From 1st condition:

3^(x+1)=81
Take log on both sides,
➡ log [3^(x+1)]=log81
Use the property: log(x^a)=a logx
➡ (x+1) log 3=log(3⁴)
➡ (x+1) log 3=4×log 3
➡ (x+1)=4 (log 3 /log 3)
➡ x+1=4
➡ x=3➡↪➡↪ ANS

From 2nd condition, (Same process are repeated)

81^(x-y)=3
➡ 3^4(x-y)=3
➡ log [3^4(3-y)]=log 3
➡ 4(3-y) log 3=log 3
➡ (3-y)=(log 3)/(4log 3)
➡ 3-y=(1/4)
➡ y=11/4 ➡↪➡↪ ANS
