A box sliding on a horizontal frictionless surface runs into a fixed spring, compressing it a distance x1 from its relaxed posit

inn [45]

Answer:twice of initial value

Explanation:

Given

spring compresses $x_1$ distance for some initial speed

Suppose v is the initial speed and k be the spring constant

Applying conservation of energy

kinetic energy converted into spring Elastic potential energy

$\dfrac{1}{2}mv^2=\dfrac{1}{2}kx_1^2----1$

When speed doubles

$\dfrac{1}{2}m(2v)^2=\dfrac{1}{2}kx_2^2----2$

divide 1 and 2

$\dfrac{1}{4}=\dfrac{x_1^2}{x_2^2}$

$x_2=2x_1$

Therefore spring compresses twice the initial value

3. When 10^14 electrons are removed from a neutral metal sphere, the charge on the sphere

Umnica [9.8K]

Answer:

Β. 16 με

Explanation:

Data provided in the question

Number of electrons removed = 10^14

And, the charge on one electron = $1.6\times 10^ {-19C}$

Based on the above information, the charged on the sphere is

Therefore when we remove the electrons

So, the equation would be

$10^{14} \times 1.6 \times 10^{-19 C}$

= $1.6 \times 10$

Therefore the same amount of the positive charged would be developed

Hence, the correct option is B.
