Answer:
Speed of the ball in position D
<u>Explanation:</u>
Given:
Position of B=11.3
Position of D=1.9
Velocity of B=6.2
To Find:
Velocity of D
Solution:
According to the formula, Velocity is given as
=Velocity of B
=Velocity of D
g=acceleration due to gravity=9.8 m/s^2
=Change in position of B and D
Substitute the all values in the above equation we get
Result :
The velocity of D is
Answer:
The following is the relation between electric force and field
Explanation:
Electric force is the magnitude of electrostatic forces between two charges which is directly proportional to product of both charges and inversely proportional to the square of the distance between them.
Here k is the coulumb's constant.
Where as the electric field is the electric force per unit charge. It is the function of electric force. It is the vector quantity and its direction is taken radially inward or outward depending on the nature of charge.
Its equation is
Electric Field
Electric Field units are in volts where as Electric force units are newtons.
