A test charge of +3 µC is at a point P where the electric field due to the other charges is directed to the right and has a magn

umka2103 [35]

Answer:

Electric field will remain same.

Explanation:

Given that

At initial condition ,charge q = +3μ C

Electric field E = 4106 N/c

As we know that

Electric field due to charge q

$E=\dfrac{kq}{r^2}$

Now when charge is replaced by new charge q'= -3μ C

From the expression of electric field we can say that electric field will remain same from same quantity of electric charge.

So we can say that electric field will remain same.

At 19°C, a rod is exactly 19.11 cm long on a steel ruler. Both the rod and the ruler are placed in an oven at 280°C, where the r

Ratling [72]

Answer:

$\alpha = 4.12 \times 10^{-5} per Degree C$

Explanation:

As we know that when we increase the temperature of the rod and the ruler then in that case there will be change in the length of the both.

Due to this the ruler measurement is different from actual length of the rod

So by thermal expansion we know that

$L = L_o(1 +\alpha \Delta T)$

$L = 19.11 (1 + \alpha(280 - 19))$

$L = 19.11(1 + 261\alpha)$

Now for length of unit division of steel scale

$1 unit = 1( 1 + \alpha_s \Delta T)$

$1 unit = (1 + (11 \times 10^{-6})(280 - 19))$

$1 unit = 1.0029$

now the measured length from the scale is given as

$L_{measured} = \frac{L}{1.0029}$

$L_{measured} = \frac{19.11(1 + 261\alpha)}{1.0029}$

$19.26 = \frac{19.11(1 + 261\alpha)}{1.0029}$

$\alpha = 4.12 \times 10^{-5} per Degree C$
