Answer:
+1.33 × C and -1.33 ×
C respectively.
Explanation:
Electric potential (V) is the work done in moving a unit positive charge from infinity to a reference point within an electric field. It is measured in volts.
V = ............. 1
where: k is a constant = 9 × N
, q is the charge and r is the distance between the charges.
From equation 1,
q = ............... 2
The charge on each ball can be determined as;
given that; V = 1.2 × , k = 9 ×
N
and r = 1.00 m.
From equation 2,
q =
= 1.33 × C
Thus, the charge on the first ball is +1.33 × C, while the charge on the second ball is -1.33 ×
C.
<u>Answer:</u>
Ranks based on momentum are
<em>1. </em><em>1200 kg car going at 15 m/s.</em>
<em>2.</em><em> 15 kg meteor going at a speed of 100 m/s.</em>
<em>3. </em><em>100 kg person running at 5 m/s.</em>
<em>4.</em><em> 10000 kg train car at rest.</em>
<u>Explanation:</u>
Product of a body’s mass and velocity gives the value of its momentum. It is given by the equation
where is the mass of the object and is the velocity.
Calculating the values of momentum:
1. mass= 1200 kg, velocity= 15 m/s
2. mass= 15 kg, velocity= 1000 m/s
3. mass= 100 kg, velocity= 5 m/s
4. mass= 1000 kg, velocity= 0 m/s
