Answer with Explanation:

We are given that

Distance between two charges,d=2.55\times 10^{-2} m

a_1=4.65\times 10^3 m/s^2

a_2=8.55\times 10^3 m/s^2

Mass of particle 1=m_1=6.05\times 10^{-6} kg

a.We have to find the change on each particle .

Let q_1=q_2=q

Force ,F=\frac{kq_1q_2}{d^2}

Where k=9\times 10^9

Using the formula

F=\frac{9\times 10^9\times q^2}{(2.55\times 10^{-2})^2}

For particle 1

F=m_1a_1

F=6.05\times 10^{-6}\times 4.65\times 10^3=0.028 N

Using the value of F

0.028=\frac{9\times 10^9\times q^2}{(2.55\times 10^{-2})^2}

q^2=\frac{(2.55\times 10^{-2})^2\times 0.028}{9\times 10^9}

q=\sqrt{\frac{(2.55\times 10^{-2})^2\times 0.028}{9\times 10^9}}

q=4.5\times 10^{-8} C

q_1=q_2=4.5\times 10^{-8} C

b.m_2=\frac{F}{a_2}

Using the formula

m_2=\frac{0.028}{8.55\times 10^3}

m_2=3.3\times 10^{-6} kg

A car with a constant velocity of 22 m/s is driven for 6.8 s. How far did it travel? (V =A d/AT)
SVEN [57.7K]

Answer: 150 m

Explanation:

velocity = 22 m/s

t = 6.8 s

velocity = \frac{distance}{time}

distance = velocity × time

= 22 × 6.8

= 149.6 m

≈ 150 m

option C

How many forces are acting on a stationary raft floating in a swimming pool A1 B2 or C3
Hitman42 [59]
There are at least two forces on it, and there could be more.

Vertical forces:
-- gravity, directed downward
-- buoyant force, directed upward
These two forces must be exactly equal, so that the net
vertical force on the raft is zero.  Otherwise, it would be
accelerating either up or down.

Horizontal forces:
We know that the net horizontal force on the raft is zero. 
Otherwise, it would be accelerating horizontally.

But we don't know if there are actually no horizontal forces
at all, or a balanced group of horizontal forces, that add up
to a net force of zero.
