i have certain doubts regarding some questions and the questions are as follows:--
1.)The electric field at 20 cm from the centre of uniformly charged sphere 10 cm is E.Then at a distance of 5 cm from the centre field will be?
2.)A uniform electric field pointing in +ve x direction exists in a region. let A be the origin,B be the point on x axis at x=+1cm and C be the point on y axis at y=+1 cm.then the potential at the pont A,Band C satisfy:
a.)VA<VB b)VA>VB c.)VA<VC d.)VA>VC
3.)A given charge situated at a certain distance from an electric dipole in the end on position experience a force F,a force acting on the charge will be?
