a uniformly charged insulating spherical shell of inner radius r outer radius r2 what is the electric field

i think it because equal matrices have equal dimensions, only square matrices can be symmetric. for all indices and . every square diagonal matrix is symmetric, since all off-diagonal elements are zero. in linear algebra, a real symmetric matrix represents a self-adjoint operator over a real inner product space.

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes

need to see circuit to get time constant

current and voltage can both be different in different parts of a circuit so it matters where you place the ammeter and voltmete
