Liquid medium of dielectric constant k and of specific gravity 2, two identically charged years are suspended from a fixed point by threats of equal lengths. The angle between them is 90 degrees. In another medium of unknown dielectric, constant k , and specific gravity 4, the angle between them becomes 120 degrees. If density of material of sphere is 8 grams per cc then k is

Vishal kumar 14th Sep, 2026

Given:

Density of sphere, $\rho_s=8 \mathrm{~g} / \mathrm{cm}^3$
First medium: specific gravity $=2$, so $\rho_1=2 \mathrm{~g} / \mathrm{cm}^3$
Second medium: specific gravity $=4$, so $\rho_2=4 \mathrm{~g} / \mathrm{cm}^3$
First angle: $90^{\circ}$
Second angle: $120{ }^{\circ}$
Dielectric constants: $k$ and $k^{\prime}$

For two identical charged spheres,

$
\tan \frac{\theta}{2}=\frac{F_e}{W_{\text {effective }}}

Three charges -q1 ,q2 and -q3 are placed her shown in the figure the X component of force on minus q1 is proportional to

Sanskriti Srivastava 14th Sep, 2026

Hello Student,

To find the X-component of the force on -q1, we need to know the positions of -q1, q2 and -q3, along with the distances/angles shown in the figure. The X-component is obtained by calculating the Coulomb force due to each charge and then resolving the forces along the

The difference of two no .is 5 and the product of their no is 24 find the no

Garima 14th Sep, 2026

Hi Rajwati Km

Let the two numbers be x and y.

Given:

  • Difference = 5

  • x-y= 5

  • Product = 24

  • xy=24

From x−y=5:

x=y+5

Substitute in xy=24

y(y+5)=24

y^2+5y−24=0

Factorising:

(y+8)(y−3)=0

So, y=3 or y=-8.

Therefore, the two numbers are 8 and 3 .

Nischal Kothapalli 15th Sep, 2026

Hey there,

If you mean TG EAPCET counselling, then yes, there is a provision to modify options after freezing, but it depends on the phase and the official schedule. The counselling instructions state that frozen options can be changed through the designated process/help-line centre when the modification opportunity is provided.
