melon159 said:QQ..The electric field at a certain distance from an isolated alpha particle is 3.0 x 10^7 NC-1
What is the force on an electron when at that distance from the alpha particle??
a. 4.8 x 10^-12
b. 9.6 x 10^-12
c. 3.0 x 10^7
d. 6.0 x 10^7
hassam said:work will be integral of this F against extensiongraph equation
examfearz said:how do we solve this??
Take the resultant vector of 3 and 4 by the pythagoras theorem. The 3 and 4 N forces will be perpedicular to each other while the 5 N force will act at the vertex of it.Saturation said:How is it 0! , can someones pls show me the directions in which the 3 forces must act in order to produce a resultant of 0!?
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
