A charge of 4.5x10^-5 is placed in an electric field with a strength of 2.0x10^4 N/C. What is the electric force acting on the charge

The force of a charged particle in an electric field is given by F=qE, where q is the charge and E is the field in N/C. This gives 0.9N

explanation:

wind is defined by the direction it blows from.   for example, a wind blowing from north to south is called a northerly wind.
