A positively charged particle initially at rest on the ground accelerates upward to 200m/s in 2.60s . The particle has a charge-

Butoxors [25]

Answer:

E = 867 N/C, upward.

Explanation:

Assuming no other forces acting on the particle, it must obey Newton's 2nd Law, as follows:

$F_{net} = m*a (1)$

There are two forces acting on the particle in the vertical direction, one due to the electric field, and the other due to gravity.
Since the particle is positively charged, assuming that the electric field aims upward, we can write the following expression for the left side of (1):

$F_{net} = q*E - m*g = m*a (2)$

Since we know that q/m = 0.1 C/kg,
⇒ q = 0.1m C/kg
Replacing this value of q in (2), and simplifying masses, we get:

$F_{net} = 0.1 *E - 9.8 m/s2 = a (3)$

We can find the value of a, simply applying the definition of acceleration:

$a =\frac{\Delta v}{\Delta t} = \frac{200m/s}{2.6s} =76.9 m/s2 (4)$

Replacing (4) in (3) and solving for E, we get:
E = 867.2 N/C, upward.

Two planets are orbiting a star in a distant galaxy the first has a semimajor axis of 150 x 10^6 km an eccentricity of 0. 20 and

e-lub [12.9K]

For two planets orbiting a star in a distant galaxy, having the first semimajor axis of 150 x 10^6 km, the period of the second plane is mathematically given as

T=2.2earth year

<h3>What is the period of the second planet?</h3>

Generally, the equation for the time period is mathematically given as

$T^{2} \appox a^{3}$

Therefore, for planet one

$1^2\approx (150 x 10^6)^3$

In conclusion, For planet 2

T^2=(250/150)^3

T=√4.632

T=2.2earth year
