Which of the following is a true statement? a. it takes two charges to create an electric field b. electric field lines cross if they are between two like charges c. how closely packed the electric field lines are indicates the strength of the electric field d. electric field lines point toward positive charges

C. How closely packed the electric field lines are indicates the strength of the electric field

Explanation:

Lets discuss ll statements

A. it takes two charges to create an electric field

This is incorrect statement as the field near any charge particle is known as electric field

B. Electric field lines cross if they are between two like charges

This is incorrect statement because Electric field lines never intersects with each other because at the point of intersection there exist two directions

C. How closely packed the electric field lines are indicates the strength of the electric field

This is correct statement because field lines density is proportional to the electric field intensity

D. electric field lines point toward positive charges

Incorrect statement because electric field lines start from positive charge and end at negative charge always

temp rises, and expansion

which three statements are true about all alloys?
