State and apply the relation between electric force and electric field.
1 answer:
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.

We have the following data:
the mass of the raft
the force applied by Sawyer
the raft's final speed
the raft's initial speed (assuming it starts from rest)
We have to find the time
Well, according to Newton's second law of motion we have:
(1)
Where is the acceleration, which can be expressed as:
