k thanks did u got q1) b ? and c? and if u got it help m ???
hai damon this integral is correct for part b F = 1.2 t^2 - 10(3)(.2) = 1.2t^2-6 integral F dt = 1.2 t^2/3 - 6 t ????
that's is grt formula i got it correct using that formula! hai Greco help for q8?
q1 a) F = dp/dt dp = Fdt ∫dp = ∫Fdt p_f - p_i = ∫βt²dt p_f - 0 = (β/3)(t_f)^3 - (β/3)(t_i)^3 no idea for part b) and c) any help ???
hai unrickross THX foR 5QUESTION I got green check !!!
Oh God unrickross i made mistake on my sign but the last ans is correct so it would be Distance between charges is d=sqrt{3²+3²} =4.24 cm x=d/2 =4.24/2 =2.12 cm =0.0212 m E=kq₁/x²+kq₂/x² = =k12e/x²+k3e/x²=k15e/x²=
unrickross ! first tell me if u got green check on that 4th question better i have to explain !!! so what about 5th question ???
hai Unrickross !!! i need ans for 5th question ??? 5??
hai Unrickross 4th question ans is Distance between charges is d=sqrt{3²+3²} =4.24 cm x=d/2 =4.24/2 =2.12 cm =0.0212 m E=kq₁/x²-kq₂/x² = =k12e/x²+k3e/x²=k9e/x²= =9•10⁹•15•1.6•10⁻¹⁹/0.0212²= =4.8•10⁻⁵ N/C try this !!!
hai did u done for 5question What is the magnitude of the net electrostatic force a Boron nucleus would experience at the point halfway between the Magnesium nucleus and the 3e charge on the y axis in N?
hai asha for 7) tan(theta)=(E*q)/(m*g) and i not yet done for 6 question if u got correct ans help me ??? also for 5 question if u got it correct help me ???? 7)tan(theta)=(E*q)/(m*g) 6)?? 5)??
What is the magnitude of the net electrostatic force a Boron nucleus would experience at the point halfway between the Magnesium nucleus and the 3e charge on the y axis in N?
What is the magnitude of the net electrostatic force a Boron nucleus would experience at the point halfway between the Magnesium nucleus and the 3e charge on the y axis in N?
Hai is check incorrect can u plz check if u write it correct and thx !!!
An insulating sphere of mass m and positive charge q is attached to a spring with length h and spring constant ks and is at equilibrium as shown below: An infinitely long wire with positive linear charge density λ is placed a distance l away from the
thank bro !!! but for b)is E(0.05) = k*1e-5/(0.05^2)=3.6e7 C
any hint how i can solve this What is the magnitude of the net electrostatic force a Boron nucleus would experience at the point halfway between the Magnesium nucleus and the 3e charge on the y axis in N? ???

hai why is marked incorrect did u get green check on this question ?? and thx for support
hai bob what the charge enclosed on this formula E=k*chargeenclosed/distance from center. ??? i used 10microC but give wrong ans . and did u got ans for a???? i checked 20microC and give wrong ans
